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

抛弃java

Answer 2

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