我尝试为{i} xlsx创建xmlbeans 2.6.0.jar个文件来创建一个项目。当我尝试重新启动glassfish时，我收到以下错误消息。请任何人通过这个并帮助我

Error:

a value of type [java.util.ArrayList] (value

the web application was stopped. Threads are going to be renewed over 
time to try and avoid a probable memory leak.

Answer 1

这是a known issue of XML Beans库。

您可以尝试关注 Jochen Kemnade 的建议：

作为一种解决方法，我将POI转换移动到专用线程池，当我的webapp上下文被销毁时我关闭了该线程池。这样，所有泄漏都会随着池而下降，并且Tomcat的处理程序线程保持干净

完成内部工作并Executor并摆脱它。

Answer 2

自从XMLBeans 3.1.0（从Apache POI 4.1.0开始包含）以来，就有一种方法可以从当前线程中手动清除XMLBeans中的所有线程本地变量：

org.apache.xmlbeans.ThreadLocalUtil.clearAllThreadLocals()

请参见https://issues.apache.org/jira/browse/XMLBEANS-502和http://xmlbeans.apache.org/status.html
