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

非法存取：此網路應用程式實例已被停止。無法載入com.mchange.v2.c3p0.impl.poolbackeddatasourcebasebeaninfo。最終的堆疊追蹤是由於調試目的引發的錯誤，以及試圖終止導致非法訪問的線程，並且沒有任何功能影響.。

你的專案沒有找到com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo這個包，你重新看看是不是你專案問題，如果是的話，修復之後重新發布試試看，實在不行重裝tomcat和jdk試試看

Answer 2

拋棄java

Answer 3

無法載入com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo依賴，更新下jar包看看。
