启动应用程序并立即关闭 Tomcat 后，我收到以下两个 Tomcat 警告：
Mrz 11, 2013 11:25:06 AM org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
Schwerwiegend: The web application [] created a ThreadLocal with key of type [com.sun.xml.ws.api.server.ThreadLocalContainerResolver$1] (value [com.sun.xml.ws.api.server.ThreadLocalContainerResolver$1@9be26c]) and a value of type [com.sun.xml.ws.api.server.Container.NoneContainer] (value [com.sun.xml.ws.api.server.Container$NoneContainer@4c563]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

Tomcat 拒绝关闭并挂起。我正在使用 com.sun.xml.ws.transport.http.servlet.WSSpringServlet。这个webapp应该如何正确关闭？
