Using jboss-as-7.1.1.Final

I created a subcontext to store a set of objects:

Context initialContext = new InitialContext();

Context context = initialContext.createSubcontext("java:/app/objs");

At this point I can bind and lookup just fine:

context.bind("a",a); // can be looked up as either "java:app/objs/a" or just "a" from the subcontext

According to the documentation if I use:

EventContext eventContext = (EventContext)initialContext.lookup("");

and eventContext is not null, I should be able to attach a NamingListener to get notifications.  I've tried countless permutations of where EventContext's initial context looks + where target looks, but neither the NamespaceChangeListener nor the ObjectChangeListener ever fires.

For example:

Given the above bind and eventContext:

eventContext.addNamingListener("java:app/objs/a",EventContext.OBJECT_SCOPE, new ObjectChangeListener() {...

objectChanged never fires and attaching a NamespaceChangeListener didn't fire when new objects were added.
