你好，想跟你请教个问题：druid 在 apache tomcat 里面经常要出现这样的报错，百度了很久不得其解。

信息: Illegal access: this web application instance has been stopped already.  Could not load com.mysql.jdbc.ProfilerEventHandlerFactory.  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.
