The wrapped method receives parameters - * in the form of an array of Object. - * - *

The body of the created method is a copy of the body of the method - * specified by body. However, it is wrapped in - * parameter-conversion code. - * - *

The method specified by body must have this singature: - * - *

    Object method(Object[] params, <type> cvalue) - *
- * - *

The type of the cvalue depends on - * constParam. - * If constParam is null, the signature - * must be: - * - *

    Object method(Object[] params)
- * - *

The method body copied from body is wrapped in - * parameter-conversion code, which converts parameters specified by - * parameterTypes into an array of Object. - * The returned value is also converted from the Object - * type to the type specified by returnType. Thus, - * the resulting method body is as follows: - * - * 

    Object[] params = new Object[] { p0, p1, ... };
-     * <type> cvalue = <constant-value>;
-     *  ... copied method body ...
-     * Object result = <returned value>
-     * return (<returnType>)result;
-     *
- * - *

The variables p0, p2, ... represent - * formal parameters of the created method. - * The value of cvalue is specified by - * constParam. - * - *

If the type of a parameter or a returned value is a primitive - * type, then the value is converted into a wrapper object such as - * java.lang.Integer. If the type of the returned value - * is void, the returned value is discarded. - * - *

Example: - * - * 

    ClassPool pool = ... ;
-     * CtClass vec = pool.makeClass("intVector");
-     * vec.setSuperclass(pool.get("java.util.Vector"));
-     * CtMethod addMethod = pool.getMethod("Sample", "add0");
-     *
-     * CtClass[] argTypes = { CtClass.intType };
-     * CtMethod m = CtNewMethod.wrapped(CtClass.voidType, "add", argTypes,
-     *                                  null, addMethod, null, vec);
-     * vec.addMethod(m);
- * - *

where the class Sample is as follows: - * - * 

    public class Sample extends java.util.Vector {
-     *     public Object add0(Object[] args) {
-     *         super.addElement(args[0]);
-     *         return null;
-     *     }
-     * }
- * - *

This program produces a class intVector: - * - * 

    public class intVector extends java.util.Vector {
-     *     public void add(int p0) {
-     *         Object[] args = new Object[] { p0 };
-     *         // begin of the copied body
-     *         super.addElement(args[0]);
-     *         Object result = null;
-     *         // end
-     *     }
-     * }
- * - *

Note that the type of the parameter to add() depends - * only on the value of argTypes passed to - * CtNewMethod.wrapped(). Thus, it is easy to - * modify this program to produce a - * StringVector class, which is a vector containing - * only String objects, and other vector classes. - * - * @param returnType the type of the returned value. - * @param mname the method name. - * @param parameterTypes a list of the parameter types. - * @param exceptionTypes a list of the exception types. - * @param body the method body - * (must not be a static method). - * @param constParam the constant parameter - * (maybe null). - * @param declaring the class to which the created method is - * added. - */ - public static com.fr.third.javassist.CtMethod wrapped(com.fr.third.javassist.CtClass returnType, - String mname, - com.fr.third.javassist.CtClass[] parameterTypes, - com.fr.third.javassist.CtClass[] exceptionTypes, - CtMethod body, ConstParameter constParam, - CtClass declaring) - throws CannotCompileException - { - return CtNewWrappedMethod.wrapped(returnType, mname, parameterTypes, - exceptionTypes, body, constParam, declaring); - } -} diff --git a/fine-javassist/src/main/java/com/fr/third/javassist/CtNewNestedClass.java b/fine-javassist/src/main/java/com/fr/third/javassist/CtNewNestedClass.java deleted file mode 100644 index 3c211d58f..000000000 --- a/fine-javassist/src/main/java/com/fr/third/javassist/CtNewNestedClass.java +++ /dev/null @@ -1,67 +0,0 @@ -/* - * Javassist, a Java-bytecode translator toolkit. - * Copyright (C) 1999- Shigeru Chiba.

This is a sample class loader using ClassPool. - * Unlike a regular class loader, this class loader obtains bytecode - * from a ClassPool. - * - *

Note that Javassist can be used without this class loader; programmers - * can define their own versions of class loader. They can run - * a program even without any user-defined class loader if that program - * is statically translated with Javassist. - * This class loader is just provided as a utility class. - * - *

Suppose that an instance of MyTranslator implementing - * the interface Translator is responsible for modifying - * class files. - * The startup program of an application using MyTranslator - * should be something like this: - * - * 

    - * import javassist.*;
- *
- * public class Main {
- *   public static void main(String[] args) throws Throwable {
- *     MyTranslator myTrans = new MyTranslator();
- *     ClassPool cp = ClassPool.getDefault();
- *     Loader cl = new Loader(cp);
- *     cl.addTranslator(cp, myTrans);
- *     cl.run("MyApp", args);
- *   }
- * }
- *
- * - *

Class MyApp is the main program of the application. - * - *

This program should be executed as follows: - * - * 

    - * % java Main arg1 arg2...
- *
- * - *

It modifies the class MyApp with a MyTranslator - * object before the JVM loads it. - * Then it calls main() in MyApp with arguments - * arg1, arg2, ... - * - *

This program execution is equivalent to: - * - * 

    - * % java MyApp arg1 arg2...
- *
- * - *

except that classes are translated by MyTranslator - * at load time. - * - *

If only a particular class must be modified when it is loaded, - * the startup program can be simpler; MyTranslator is - * unnecessary. For example, if only a class test.Rectangle - * is modified, the main() method above will be the following: - * - * 

    - * ClassPool cp = ClassPool.getDefault();
- * Loader cl = new Loader(cp);
- * CtClass ct = cp.get("test.Rectangle");
- * ct.setSuperclass(cp.get("test.Point"));
- * cl.run("MyApp", args);
- * - *

This program changes the super class of the test.Rectangle - * class. - * - *

Note 1: - * - *

This class loader does not allow the users to intercept the loading - * of java.* and javax.* classes (and - * sun.*, org.xml.*, ...) unless - * Loader.doDelegation is false. This is because - * the JVM prohibits a user class loader from loading a system class. - * Also see Note 2. - * If this behavior is not appropriate, a subclass of Loader - * must be defined and loadClassByDelegation() must be overridden. - * - *

Note 2: - * - *

If classes are loaded with different class loaders, they belong to - * separate name spaces. If class C is loaded by a class - * loader CL, all classes that the class C - * refers to are also loaded by CL. However, if CL - * delegates the loading of the class C to CL', - * then those classes that the class C refers to - * are loaded by a parent class loader CL' - * instead of CL. - * - *

If an object of class C is assigned - * to a variable of class C belonging to a different name - * space, then a ClassCastException is thrown. - * - *

Because of the fact above, this loader delegates only the loading of - * javassist.Loader - * and classes included in package java.* and - * javax.* to the parent class - * loader. Other classes are directly loaded by this loader. - * - *

For example, suppose that java.lang.String would be loaded - * by this loader while java.io.File is loaded by the parent - * class loader. If the constructor of java.io.File is called - * with an instance of java.lang.String, then it may throw - * an exception since it accepts an instance of only the - * java.lang.String loaded by the parent class loader. - * - * @see com.fr.third.javassist.ClassPool - * @see Translator - */ -public class Loader extends ClassLoader { - private Hashtable notDefinedHere; // must be atomic. - private Vector notDefinedPackages; // must be atomic. - private com.fr.third.javassist.ClassPool source; - private Translator translator; - private ProtectionDomain domain; - - /** - * Specifies the algorithm of class loading. - * - *

To obtain an AnnotationAttribute object, invoke - * getAttribute(AnnotationsAttribute.visibleTag) - * in ClassFile, MethodInfo, - * or FieldInfo. The obtained attribute is a - * runtime visible annotations attribute. - * If the parameter is - * AnnotationAttribute.invisibleTag, then the obtained - * attribute is a runtime invisible one. - * - *

For example, - * - * 

    - * import javassist.bytecode.annotation.Annotation;
- *    :
- * CtMethod m = ... ;
- * MethodInfo minfo = m.getMethodInfo();
- * AnnotationsAttribute attr = (AnnotationsAttribute)
- *         minfo.getAttribute(AnnotationsAttribute.invisibleTag);
- * Annotation an = attr.getAnnotation("Author");
- * String s = ((StringMemberValue)an.getMemberValue("name")).getValue();
- * System.out.println("@Author(name=" + s + ")");
- *
- * - *

This code snippet retrieves an annotation of the type Author - * from the MethodInfo object specified by minfo. - * Then, it prints the value of name in Author. - * - *

If the annotation type Author is annotated by a meta annotation: - * - * 

    - * @Retention(RetentionPolicy.RUNTIME)
- *
- * - *

Then Author is visible at runtime. Therefore, the third - * statement of the code snippet above must be changed into: - * - * 

    - * AnnotationsAttribute attr = (AnnotationsAttribute)
- *         minfo.getAttribute(AnnotationsAttribute.visibleTag);
- *
- * - *

The attribute tag must be visibleTag instead of - * invisibleTag. - * - *

If the member value of an annotation is not specified, the default value - * is used as that member value. If so, getMemberValue() in - * Annotation returns null - * since the default value is not included in the - * AnnotationsAttribute. It is included in the - * AnnotationDefaultAttribute of the method declared in the - * annotation type. - * - *

If you want to record a new AnnotationAttribute object, execute the - * following snippet: - * - * 

    - * ClassFile cf = ... ;
- * ConstPool cp = cf.getConstPool();
- * AnnotationsAttribute attr
- *     = new AnnotationsAttribute(cp, AnnotationsAttribute.visibleTag);
- * Annotation a = new Annotation("Author", cp);
- * a.addMemberValue("name", new StringMemberValue("Chiba", cp));
- * attr.setAnnotation(a);
- * cf.addAttribute(attr);
- * cf.setVersionToJava5();
- *
- * - *

Otherwise, it is not necessary. - * - * @see AnnotationDefaultAttribute - * @see com.fr.third.javassist.bytecode.annotation.Annotation - */ -public class AnnotationsAttribute extends com.fr.third.javassist.bytecode.AttributeInfo { - /** - * The name of the RuntimeVisibleAnnotations attribute. - */ - public static final String visibleTag = "RuntimeVisibleAnnotations"; - - /** - * The name of the RuntimeInvisibleAnnotations attribute. - */ - public static final String invisibleTag = "RuntimeInvisibleAnnotations"; - - /** - * Constructs a Runtime(In)VisibleAnnotations_attribute. - * - * @param cp constant pool - * @param attrname attribute name (visibleTag or - * invisibleTag). - * @param info the contents of this attribute.

- *         if (m.getClassName().equals("Point")) {

- *     }
- * });
- *
- * - *

To run a program, say MyApp, - * including a reflective class, - * you must write a start-up program as follows: - * - * 

    - * public class Main {
- *   public static void main(String[] args) throws Throwable {
- *     javassist.tools.reflect.Loader cl
- *         = (javassist.tools.reflect.Loader)Main.class.getClassLoader();
- *     cl.makeReflective("Person", "MyMetaobject",
- *                       "javassist.tools.reflect.ClassMetaobject");
- *     cl.run("MyApp", args);
- *   }
- * }
- *
- * - *

Then run this program as follows: - * - * 

    % java javassist.tools.reflect.Loader Main arg1, ...
- * - *

This command runs Main.main() with arg1, ... - * and Main.main() runs MyApp.main() with - * arg1, ... - * The Person class is modified - * to be a reflective class. Method calls on a Person - * object are intercepted by an instance of MyMetaobject. - * - *

Also, you can run MyApp in a slightly different way: - * - * 

    - * public class Main2 {
- *   public static void main(String[] args) throws Throwable {
- *     javassist.tools.reflect.Loader cl = new javassist.tools.reflect.Loader();
- *     cl.makeReflective("Person", "MyMetaobject",
- *                       "javassist.tools.reflect.ClassMetaobject");
- *     cl.run("MyApp", args);
- *   }
- * }
- *
- * - *

This program is run as follows: - * - * 

    % java Main2 arg1, ...
- * - *

The difference from the former one is that the class Main - * is loaded by javassist.tools.reflect.Loader whereas the class - * Main2 is not. Thus, Main belongs - * to the same name space (security domain) as MyApp - * whereas Main2 does not; Main2 belongs - * to the same name space as javassist.tools.reflect.Loader. - * For more details, - * see the notes in the manual page of javassist.Loader. - * - *

The class Main2 is equivalent to this class: - * - * 

    - * public class Main3 {
- *   public static void main(String[] args) throws Throwable {
- *     Reflection reflection = new Reflection();
- *     javassist.Loader cl
- *         = new javassist.Loader(ClassPool.getDefault(reflection));
- *     reflection.makeReflective("Person", "MyMetaobject",
- *                               "javassist.tools.reflect.ClassMetaobject");
- *     cl.run("MyApp", args);
- *   }
- * }
- *
- * - *

Note: - * - *

javassist.tools.reflect.Loader does not make a class reflective - * if that class is in a java.* or - * javax.* pacakge because of the specifications - * on the class loading algorithm of Java. The JVM does not allow to - * load such a system class with a user class loader. - * - *

This factory generates a class that extends the given super class and implements - * the given interfaces. The calls of the methods inherited from the super class are - * forwarded and then invoke() is called on the method handler - * associated with instances of the generated class. The calls of the methods from - * the interfaces are also forwarded to the method handler. - * - *

For example, if the following code is executed, - * - * 

    - * ProxyFactory f = new ProxyFactory();
- * f.setSuperclass(Foo.class);
- * f.setFilter(new MethodFilter() {
- *     public boolean isHandled(Method m) {
- *         // ignore finalize()
- *         return !m.getName().equals("finalize");
- *     }
- * });
- * Class c = f.createClass();
- * MethodHandler mi = new MethodHandler() {
- *     public Object invoke(Object self, Method m, Method proceed,
- *                          Object[] args) throws Throwable {
- *         System.out.println("Name: " + m.getName());
- *         return proceed.invoke(self, args);  // execute the original method.
- *     }
- * };
- * Foo foo = (Foo)c.newInstance();
- * ((Proxy)foo).setHandler(mi);
- *
- * - *

Here, Method is java.lang.reflect.Method.

- * - *

Then, the following method call will be forwarded to MethodHandler - * mi and prints a message before executing the originally called method - * bar() in Foo. - * - * 

    - * foo.bar();
- *
- * - *

The last three lines of the code shown above can be replaced with a call to - * the helper method create, which generates a proxy class, instantiates - * it, and sets the method handler of the instance: - * - * 

    - *     :
- * Foo foo = (Foo)f.create(new Class[0], new Object[0], mi);
- *
- * - *

To change the method handler during runtime, - * execute the following code: - * - * 

    - * MethodHandler mi = ... ;    // alternative handler
- * ((Proxy)foo).setHandler(mi);
- *
- * - *

If setHandler is never called for a proxy instance then it will - * employ the default handler which proceeds by invoking the original method. - * The behaviour of the default handler is identical to the following - * handler: - * - * 

    - * class EmptyHandler implements MethodHandler {
- *     public Object invoke(Object self, Method m,
- *                          Method proceed, Object[] args) throws Exception {
- *         return proceed.invoke(self, args);
- *     }
- * }
- *
- * - *

A proxy factory caches and reuses proxy classes by default. It is possible to reset - * this default globally by setting static field {@link ProxyFactory#useCache} to false. - * Caching may also be configured for a specific factory by calling instance method - * {@link ProxyFactory#setUseCache(boolean)}. It is strongly recommended that new clients - * of class ProxyFactory enable caching. Failure to do so may lead to exhaustion of - * the heap memory area used to store classes. - * - *

Caching is automatically disabled for any given proxy factory if deprecated instance - * method {@link ProxyFactory#setHandler(MethodHandler)} is called. This method was - * used to specify a default handler which newly created proxy classes should install - * when they create their instances. It is only retained to provide backward compatibility - * with previous releases of javassist. Unfortunately,this legacy behaviour makes caching - * and reuse of proxy classes impossible. The current programming model expects javassist - * clients to set the handler of a proxy instance explicitly by calling method - * {@link com.fr.third.javassist.util.proxy.Proxy#setHandler(MethodHandler)} as shown in the sample code above. New - * clients are strongly recommended to use this model rather than calling - * {@link ProxyFactory#setHandler(MethodHandler)}. - * - *

A proxy object generated by ProxyFactory is serializable - * if its super class or any of its interfaces implement java.io.Serializable. - * However, a serialized proxy object may not be compatible with future releases. - * The serialization support should be used for short-term storage or RMI. - * - *

For compatibility with older releases serialization of proxy objects is implemented by - * adding a writeReplace method to the proxy class. This allows a proxy to be serialized - * to a conventional {@link java.io.ObjectOutputStream} and deserialized from a corresponding - * {@link java.io.ObjectInputStream}. However this method suffers from several problems, the most - * notable one being that it fails to serialize state inherited from the proxy's superclass. - *

- * An alternative method of serializing proxy objects is available which fixes these problems. It - * requires inhibiting generation of the writeReplace method and instead using instances of - * {@link ProxyObjectOutputStream} and {@link ProxyObjectInputStream} - * (which are subclasses of {@link java.io.ObjectOutputStream} and {@link java.io.ObjectInputStream}) - * to serialize and deserialize, respectively, the proxy. These streams recognise javassist proxies and ensure - * that they are serialized and deserialized without the need for the proxy class to implement special methods - * such as writeReplace. Generation of the writeReplace method can be disabled globally by setting static field - * {@link ProxyFactory#useWriteReplace} to false. Alternatively, it may be - * configured per factory by calling instance method {@link ProxyFactory#setUseWriteReplace(boolean)}. - * - * @see MethodHandler - * @since 3.1 - * @author Muga Nishizawa - * @author Shigeru Chiba - * @author Andrew Dinn - */ -public class ProxyFactory { - private Class superClass; - private Class[] interfaces; - private com.fr.third.javassist.util.proxy.MethodFilter methodFilter; - private MethodHandler handler; // retained for legacy usage - private List signatureMethods; - private boolean hasGetHandler; - private byte[] signature; - private String classname; - private String basename; - private String superName; - private Class thisClass; - /** - * per factory setting initialised from current setting for useCache but able to be reset before each create call - */ - private boolean factoryUseCache; - /** - * per factory setting initialised from current setting for useWriteReplace but able to be reset before each create call - */ - private boolean factoryWriteReplace; - - - /** - * If the value of this variable is not null, the class file of - * the generated proxy class is written under the directory specified - * by this variable.

- * {@link Transmitter} is internal manipulation api for framework/middleware integration; - * In general, you will never use it in the biz/application code! - * - *

Framework/Middleware integration to TTL transmittance

- * Below is the example code: - * - * 

-     * ///////////////////////////////////////////////////////////////////////////
-     * // in thread A, capture all TransmittableThreadLocal values of thread A
-     * ///////////////////////////////////////////////////////////////////////////
-     *
-     * Object captured = Transmitter.capture(); // (1)
-     *
-     * ///////////////////////////////////////////////////////////////////////////
-     * // in thread B
-     * ///////////////////////////////////////////////////////////////////////////
-     *
-     * // replay all TransmittableThreadLocal values from thread A
-     * Object backup = Transmitter.replay(captured); // (2)
-     * try {
-     *     // your biz logic, run with the TransmittableThreadLocal values of thread B
-     *     System.out.println("Hello");
-     *     // ...
-     *     return "World";
-     * } finally {
-     *     // restore the TransmittableThreadLocal of thread B when replay
-     *     Transmitter.restore(backup); (3)
-     * }
-     *
- *

- * see the implementation code of {@link TtlRunnable} and {@link TtlCallable} for more actual code sample. - *

- * Of course, {@link #replay(Object)} and {@link #restore(Object)} operation can be simplified by util methods - * {@link #runCallableWithCaptured(Object, Callable)} or {@link #runSupplierWithCaptured(Object, Supplier)} - * and the adorable {@code Java 8 lambda syntax}. - *

- * Below is the example code: - * - * 


-     * ///////////////////////////////////////////////////////////////////////////
-     * // in thread A, capture all TransmittableThreadLocal values of thread A
-     * ///////////////////////////////////////////////////////////////////////////
-     *
-     * Object captured = Transmitter.capture(); // (1)
-     *
-     * ///////////////////////////////////////////////////////////////////////////
-     * // in thread B
-     * ///////////////////////////////////////////////////////////////////////////
-     *
-     * String result = runSupplierWithCaptured(captured, () -> {
-     *      // your biz logic, run with the TransmittableThreadLocal values of thread A
-     *      System.out.println("Hello");
-     *      ...
-     *      return "World";
-     * }); // (2) + (3)
-     *
- *

- * The reason of providing 2 util methods is the different {@code throws Exception} type - * so as to satisfy your biz logic({@code lambda}): - *

    - *
  1. {@link #runCallableWithCaptured(Object, Callable)}: {@code throws Exception}
    2. - *
  2. {@link #runSupplierWithCaptured(Object, Supplier)}: No {@code throws}
    3. - *
- *

- * If you need the different {@code throws Exception} type, - * you can define your own util method(function interface({@code lambda})) with your own {@code throws Exception} type. - * - *

ThreadLocal Integration

- * If you can not rewrite the existed code which use {@link ThreadLocal} to {@link TransmittableThreadLocal}, - * register the {@link ThreadLocal} instances via the methods - * {@link #registerThreadLocal(ThreadLocal, TtlCopier)}/{@link #registerThreadLocalWithShadowCopier(ThreadLocal)} - * to enhance the Transmittable ability for the existed {@link ThreadLocal} instances. - *

- * Below is the example code: - * - * 


-     * // the value of this ThreadLocal instance will be transmitted after registered
-     * Transmitter.registerThreadLocal(aThreadLocal, copyLambda);
-     *
-     * // Then the value of this ThreadLocal instance will not be transmitted after unregistered
-     * Transmitter.unregisterThreadLocal(aThreadLocal);
-     *
- * - * Caution:
- * If the registered {@link ThreadLocal} instance is not {@link InheritableThreadLocal}, - * the instance can NOT {@code inherit} value from parent thread(aka. the inheritable ability)! - * - * @author Yang Fang (snoop dot fy at gmail dot com) - * @author Jerry Lee (oldratlee at gmail dot com) - * @see TtlRunnable - * @see TtlCallable - * @since 2.3.0 - */ - public static class Transmitter { - /** - * Capture all {@link TransmittableThreadLocal} and registered {@link ThreadLocal} values in the current thread. - * - * @return the captured {@link TransmittableThreadLocal} values - * @since 2.3.0 - */ - - public static Object capture() { - return new Snapshot(captureTtlValues(), captureThreadLocalValues());

TTL Agent configuration

- * Configure TTL agent via agent arguments, format is {@code k1:v1,k2:v2}. Below is available configuration keys. - * - *

Disable inheritable for thread pool

- *

- * Enable "disable inheritable" for thread pool, config by key {@code ttl.agent.disable.inheritable.for.thread.pool}. - * When no configuration for this key, default does not enabled. Since version {@code 2.10.1}. - * - *

    - *
  • rewrite the {@link java.util.concurrent.ThreadFactory} constructor parameter - * of {@link java.util.concurrent.ThreadPoolExecutor} - * to {@link DisableInheritableThreadFactory} - * by util method {@link TtlExecutors#getDisableInheritableThreadFactory(java.util.concurrent.ThreadFactory)}. - *
    • - *
  • rewrite the {@link java.util.concurrent.ForkJoinPool.ForkJoinWorkerThreadFactory} constructor parameter - * of {@link java.util.concurrent.ForkJoinPool} - * to {@link DisableInheritableForkJoinWorkerThreadFactory} - * by util method {@link TtlForkJoinPoolHelper#getDisableInheritableForkJoinWorkerThreadFactory(java.util.concurrent.ForkJoinPool.ForkJoinWorkerThreadFactory)}. - *
    • - *
- * More info about "disable inheritable" see {@link TransmittableThreadLocal}. - *

- * Configuration example:
- * {@code -javaagent:/path/to/transmittable-thread-local-2.x.x.jar=ttl.agent.disable.inheritable.for.thread.pool:true} - * - *

The log configuration

- * The log of TTL Java Agent is config by key {@code ttl.agent.logger}. Since version {@code 2.6.0}. - * - *
    - *
  • {@code ttl.agent.logger : STDERR}
    - * only log to {@code stderr} when error. - * This is default, when no/unrecognized configuration for key {@code ttl.agent.logger}.
    • - *
  • {@code ttl.agent.logger : STDOUT}
    - * Log to {@code stdout}, more info than {@code ttl.agent.logger:STDERR}; This is needed when developing.
    • - *
- *

- * configuration example: - *

    - *
  • {@code -javaagent:/path/to/transmittable-thread-local-2.x.x.jar}
    • - *
  • {@code -javaagent:/path/to/transmittable-thread-local-2.x.x.jar=ttl.agent.logger:STDOUT}
    • - *
- * - *

Enable/disable TimerTask class decoration

- * Enable/disable TimerTask class decoration is config by key {@code ttl.agent.enable.timer.task}. - * Since version {@code 2.7.0}. - *

- * When no configuration for this key, default is enabled.
- * Note: Since version {@code 2.11.2} the default value is {@code true}(enable TimerTask class decoration); - * Before version {@code 2.11.1} default value is {@code false}. - *

- * Configuration example: - *

    - *
