我用定时器启动应用的时候发现内存泄漏，具体报错如下：

十月 30, 2015 2:30:12 下午 org.apache.catalina.startup.HostConfig undeploy

信息: Undeploying context [/ChinaMoney Maven Webapp]

十月 30, 2015 2:30:15 下午 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc

严重: The web application [/ChinaMoney Maven Webapp] registered the JDBC driver [net.sourceforge.jtds.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.

十月 30, 2015 2:30:15 下午 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads

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

十月 30, 2015 2:30:15 下午 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads

严重: The web application [/ChinaMoney Maven Webapp] appears to have started a thread named [startQuertz_Worker-2] but has failed to stop it. This is very likely to create a memory leak.

定时器定义如下：

30 38 09 * * ?

class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

buy_it_now

2

org.quartz.plugins.management.ShutdownHookPlugin

true

true

请各位大神看看问题出在哪里了~跪谢！！！
