> 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.
