Could not load oracle/sql/converter_xcharset/lx20354.glb.

一、错误描述：

此错误导致了web 服务器停止服务，应该属于“不能连接Oracle”的错误。

二、具体错误信息：

信息: Illegal access: this web application instance has been stopped already.  Could not load oracle/sql/converter_xcharset/lx20354.glb.  The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

三、解决方法

现在把它们删除。
