tomcat 监听器启动线程导致tomcat只允许线程的run方法，不能访问项目
项目简介：Jsp3.0+dbcp连接池1.4+tomcat8.0
因连接池泄露，有些connection无法关闭，想可以手动kill掉那些连接时间超过2分钟的Connection连接。然后写了一个线程，将它挂在ServletContextListener监听器下，然后tomcat一启动，tomcat会被该线程卡住，出现一直执行线程，而不继续加载项目的情况，导致项目无法访问，想请问下，这种情况该怎么办。怎么改这种模式才是对的。
tomcat启动错误：

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.kill 5 ;kill 6 ;kill 7 ;kill 5 ;kill 6 ;kill 7 ;代码如下：
