java - tomcat 报错，导致服务器老是死机，只有重启，求解？

Question

Illegal access: this web application instance has been stopped already. Could not load com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo. 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.

报的这个错！！！！！！！！

Answer 1

非法访问：此Web应用程序实例已被停止。无法加载com.mchange.v2.c3p0.impl.poolbackeddatasourcebasebeaninfo。最终的堆栈跟踪是由于调试目的引发的错误，以及试图终止导致非法访问的线程，并且没有任何功能影响.。

你的项目没有找到com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo这个包，你重新看看是不是你项目问题，如果是的话，修复之后重新发布试试看，实在不行重装tomcat和jdk试试看

Answer 2

抛弃java

Answer 3

无法加载com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo依赖，更新下jar包看看。
