每次重新部署后，我在日志中看到以下消息。

INFO: Reloading Context with name [/x1Application] has started SEVERE: The web application [/x1Application] appears to have started a thread named [Mojarra-WebResourceMonitor-1-thread-1] but has failed to stop it. This is very likely to create a memory leak. SEVERE: The web application [/x1Application] appears to have started a thread named [Hector.me.prettyprint.cassandra.connection.CassandraHostRetryService-1] but has failed to stop it. This is very likely to create a memory leak.

最终在1-2个热部署之后，服务器停止响应，并且我收到PermGen空间错误
