EJB3 Remoting/Security problem in JBoss with classloader isolation.

I have an application in JBoss. For some reason I had to enable classloader isolation. To do so, I had to dublicate remoting.jar inside application ear.

Now, I am trying to implement EJB3 Session Bean and after InitialContext.lookup for my session I cannot do anything with it because of:

I think cast exception on InvokerLocator to InvokerLocator cast is because security interceptors are in external class loader, while InvokerLocator is in side my isolated classloader.

How to instantiate security interceptors inside my classloader?

JBoss is 5.1.0.GA.
