Pull request #2940: KERNEL-6188 DatabaseConnectionPane中的SwingWorker问题

Merge in DESIGN/design from ~YVAN/design:release/10.0 to release/10.0

* commit 'fbee3b92776c2d04579bc719229d1ad827d33818':
  KERNEL-6188 补充泛型
  KERNEL-6188 去除无用的try-catch
  KERNEL-6188 修改一下doInBackground()方法与done()方法之间传递参数的类型，去除冗余代码
  KERNEL-6188 DatabaseConnectionPane中的SwingWorker问题 【问题原因】在Swingworker的doInBackground中更新UI会导致出现卡死等问题 【改动方案】将doInBackground中与UI交互的部分移到done方法中，在EDT线程处理UI，比较安全；另外修改了dialog.show()过时方法和一些导包相关问题
