Aki Yoshida commented on CXF-3773:
----------------------------------
This problem can happen when the container tries to stop the endpoint after its
associated bus has been stopped.
I'm fixing the clean up code of ServerImpl to prevent this problem from
happening.
> CXF unregisters MBeans for JAX-WS endpoints twice
> -------------------------------------------------
>
> Key: CXF-3773
> URL: https://issues.apache.org/jira/browse/CXF-3773
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 2.4.2
> Environment: Tomcat 6.0.33 / Spring 3.0.[56] / Java 1.[67]
> Reporter: Dominik Drzewiecki
> Assignee: Aki Yoshida
>
> MBeans created for JAX-WS endpoints do get unregistered twice during context
> shutdown.
> I've placed a breakpoint in
> {{org.apache.cxf.management.jmx.InstrumentationManagerImpl.unregister(ObjectName)}}
> and caught following stacks when reaching it. The first line shows the
> ObjectName being unregistered.
> You may notice that the first three stacks are observed during the {{CXFBus}}
> shutdown, and the fourth one during {{JAXWS22SpringEndpointImpl}}.
> The last invocation of
> {{org.apache.cxf.management.jmx.InstrumentationManagerImpl.unregister(ObjectName)}}
> results in {{javax.management.InstanceNotFoundException}} being thrown (the
> full message is {{"WARNING: Unregistering ManagedEndpoint failed.
> javax.management.InstanceNotFoundException:
> org.apache.cxf:bus.id=cxf52615653,type=Bus.Service.Endpoint,service="{http://ws.xxx.xxxxx.com/}Service",port="ServicePort"}})
> which prevents from shutting down the endpoint bean, spring context and web
> application context cleanly.
