Summary: StatefulHandleImpl not serializable
Initial Comment:
JBoss 3.0.0 final
MacOS X 10.1.5
Java 1.3.1
The class org.jboss.proxy.ejb.handle.StatefulHandleImpl is not
properly serializable because (I think) it has an
org.jboss.invocation.Invoker member. Some invoker
implementations are serializable and some are not.
I have a stateful session bean containing a collection of data
objects containing back pointers (via javax.ejb.Handle) to the
session bean.
Passivation of the session bean fails while serializing the data
objects:

The custom session object streams needed to handle remote
objects other than ejb interfaces.

I've done some more debugging.
At serialisation time, the StatefulHandleImpl invoker is an instance of
org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy, which is
Externalizable and should be OK. However, it is proxying an instance of
org.jboss.invocation.jrmp.server.JRMPInvoker which is *not* serializable.
