【Tomcat】【3】报错 Illegal access: this web application instance has been stopped already. Could not load [org.apache.commons.pool.impl.CursorableLinkedList$Cursor]

用Tomcat运行项目报错：

Illegal access: this web application instance has been stopped already. Could not load [org.apache.commons.pool.impl.CursorableLinkedList$Cursor].
The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

解决方法：

将commons-pool依赖的版本改为1.4
