There's 2 issues here:

1) The use of org.jboss.ha.framework.interfaces.LoadBalancePolicy in this annotation leaks the legacy  org.jboss.invocation.Invocation class.  My plan for dealing with this is to introduce a parent interface that doesn't include the method that leaks that type.  See http://www.jboss.com/index.html?module=bb&op=viewtopic&t=120423.  I need to do a serialization/deserialization test to confirm that won't break compatibility with existing clients.  This I'll get done this week.

2) Where does @Clustered go?  To me it seems like it would go in the ha-client library that I started to break out of the main AS codebase a while back.  That breakout was going to have to be done when we break ejb3 out of the AS codebase, and can be done sooner if need be.

Problem with this is the name of the annotation is @org.jboss.annotation.ejb.Clustered -- not a very generic name.
