Merge in CORE/base-third from ~BRYANT/base-third:research/11.0 to research/11.0 * commit 'b76d16056e9cb418e16ec3295a65c85e14dff28d': REPORT-120996 合并third REPORT-113277 Hibernate组件修复CVE漏洞 REPORT-108658 预览与导出pdf字体颜色不一致 【问题原因】字体填充颜色其实是一样的，但导出pdf后，字体存在黑色描边。 导出pdf时，若字体为粗体，会对字体进行描边。描边的颜色会使用到realPaint的颜色。在创建Graphics的时候，没有对realPaint进行初始化，正常情况下，是使用setPaint对其进行赋值。若此后再进行绘制，且没有调用setPaint方法，realPaint则为null，当字体为粗体时，会使用之前的颜色对其进行描边，字体颜色看起来会显示异常。 【改动思路】创建时，使用当前的realPaint进行初始化。 REPORT-109844 v8 linux arm 从11.4退回10.9 REPORT-109123 fine-third-11.0.jar中含有.bak文件待清理 REPORT-108344 用户密码被记录进日志，手机号邮箱被明文记录research/11.0
