查看tomcat的日記文件，看下如下信息，不知哪位大俠知道爲什麼會產生這樣的信息；
2013-7-14 6:00:14 org.apache.coyote.http11.Http11Protocol pause
信息: Pausing Coyote HTTP/1.1 on http-8088
2013-7-14 6:00:15 org.apache.catalina.core.StandardService stop
信息: Stopping service Catalina
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
嚴重: The web application [/dmscs] registered the JDBC driver [oracle.jdbc.driver.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
嚴重: The web application [/dmscs] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@ff665a]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@198c113]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
嚴重: The web application [/dmscs] created a ThreadLocal with key of type [net.sf.json.AbstractJSON$1] (value [net.sf.json.AbstractJSON$1@1abcd5e]) and a value of type [java.util.HashSet] (value [[]]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
嚴重: The web application [/dmscs] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@ff665a]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@37eaab]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
嚴重: The web application [/dmscs] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@ff665a]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@10f80a9]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-7-14 6:00:15 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
嚴重: The web application [/dmscs] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@ff665a]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@c803e6]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-7-14 6:00:16 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
嚴重: The web application [/RPT] registered the JDBC driver [oracle.jdbc.driver.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
