我正在用tomcat和jax-ws构建ws。当我停止我的应用程序时，通常是从eclipse重新部署时，我收到以下消息：

25-mar-2012 16.21.16 com.sun.xml.ws.transport.http.servlet.WSServletDelegate destroy
INFO: WSSERVLET15: JAX-WS servlet destroyed
25-mar-2012 16.21.16 com.sun.xml.ws.transport.http.servlet.WSServletContextListener contextDestroyed
INFO: WSSERVLET13: JAX-WS context listener destroyed
25-mar-2012 16.21.16 org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
GRAVE: The web application [/xccm] created a ThreadLocal with key of type [com.sun.xml.ws.api.streaming.XMLStreamReaderFactory$Default$1] (value [com.sun.xml.ws.api.streaming.XMLStreamReaderFactory$Default$1@7edeaa13]) and a value of type [com.sun.xml.internal.stream.XMLInputFactoryImpl] (value [com.sun.xml.internal.stream.XMLInputFactoryImpl@4c700677]) 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.

我发现com.sun.xml.ws.api.streaming.XMLStreamReaderFactory$Default$1被ClasspathHelper
所引用jaxws-rt.jar

但是我没有在代码中明确使用任何jax-ws类，除了：

import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.bind.JAXBContext;

据我所知tomcat加载com.sun.xml.ws.transport.http.servlet.WSServlet（和日志片段中的其他类）。

任何想法如何解决这个问题？

谢谢
