java - 由于 xmlbeans 2.6.0.jar 导致内存泄漏

Question

我正在尝试创建一个包含 xmlbeans 2.6.0.jar 的 xlsx 文件的项目。当我尝试重新启动 glassfish 时，出现以下错误。请任何人完成这个并帮助我

Error:

key of type [org.apache.xmlbeans.impl.schema.SchemaTypeLoaderImpl$1]  
(value  
[org.apache.xmlbeans.impl.schema.SchemaTypeLoaderImpl$1@4f7c1b38]) and 
a value of type [java.util.ArrayList] (value
[[java.lang.ref.SoftReference@51ec7f5b]]) but failed to remove it when 
the web application was stopped. Threads are going to be renewed over 
time to try and avoid a probable memory leak.

这是a known issue of XML Beans图书馆。

您可以尝试遵循Jochen Kemnade的建议:

As a workaround, I moved the POI transformations to a dedicated thread pool which I shutdown when my webapp context is destroyed. This way, all the leaks go down with the pool and Tomcat's handler threads stay clean

在Executor内部完成工作并摆脱它。
