Question

我在重启tomcat或停止tomcat服务器时收到这些警告和错误。这不是干扰我的项目，但我想这是严重的问题，而没有。用户增加。

P.S。我已经使用hibernate进行数据库连接，为显示表显示标记库，并使用了jsp / servlet。

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.
