tomcat 启动报错：The web application [] registered the JDBC driver [com.mysql.jdbc.Driver] but failed

服务器环境：tomcat 7.0.57+jdk1.7.0_71

问题情况描述：首先本地启动项目是正常启动，然后打war ，上传到服务器，启动项目就报下面的错误：

严重: The web application [] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

严重: The web application [] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.

严重: The web application [] appears to have started a thread named [DefaultQuartzScheduler_Worker-1] but has failed to stop it. This is very likely to create a memory leak.

严重: The web application [] appears to have started a thread named [DefaultQuartzScheduler_Worker-5] but has failed to stop it. This is very likely to create a memory leak.

严重: The web application [] appears to have started a thread named [DefaultQuartzScheduler_Worker-6] but has failed to stop it. This is very likely to create a memory leak.

解决方案：开始尝试很多种方式，降低mysql驱动，还有tomcat版本，都没效果

最终：开发环境的jdk版本必须与服务器上的jdk版本一致，编译的时候才能识别，高版本的编译下的class文件，在低版本下有些方法无法识别。
