部署在Tomcat中的dubbox，关闭时DubboShutdownHook执行失败

[amnyx]

Tomcat关闭之后，Hook执行时Load不到class

堆栈如下：

Caused by: java.lang.ClassNotFoundException: Illegal access: this web application instance has been stopped already. Could not load [com.alibaba.dubbo.registry.support.SkipFailbackWrapperException]. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.
    at org.apache.catalina.loader.WebappClassLoaderBase.checkStateForClassLoading(WebappClassLoaderBase.java:1315)
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1178)
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1139)

如何能做到真正的优雅呢
