Thread Context Classloader not set correctly on MBean notification callback

Unable to do new InitialContext() inside of a notification handler. Testing shows that the Thread.currentThread.getContextClassLoader is not set correctly. See attached example. Note the example works fine in EAP 4.3 (with the mbean annotation packages changed)

I have created a simple Annotated MBean that prints some classloader info when it starts and then registers itself to get notifications for jboss.system:type=Server. When it gets a notification, I have it print the classloader info again and the Thread CL info is not the same. Then I do a new InitialContext and it fails to find "org.jnp.interfaces.NamingContextFactory".

When the MBean starts:

Thread.currentThread().getContextClassLoader()
BaseClassLoader@ef22c9

{vfszip:/NotBackedUp/bmaxwell/server/jboss-eap-5.0.1-debug/server/active/deploy/mbean-notification-handler.jar/}

Thread.currentThread().getContextClassLoader(): vfsfile:/NotBackedUp/bmaxwell/server/jboss-eap-5.0.1-debug/server/active/conf/jndi.properties
(no exception doing Thread.currentThread().getContextClassLoader().loadClass("org.jnp.interfaces.NamingContextFactory")

When the notification is fired and the callback is invoked on the MBean:

Thread.currentThread().getContextClassLoader()
org.jboss.bootstrap.NoAnnotationURLClassLoader@1d99a4d
Thread.currentThread().getContextClassLoader(): null

Then it hits the code where I do new InitialContext().lookup("java:DefaultDS");
