trunk and 4.2.x differ slightly when it comes to org.jboss.invocation.MarshalledInvocation class.

in 4.2.x, MarshalledInvocation(Invocation invocation) constructor does:

...
this.transient_payload = invocation.transient_payload;
this.invocationContext = invocation.invocationContext;
...

whereas in trunk, the transient payload is not copied over to the MarshalledInvocation.

The discrepancy comes from:

as part of:

"JBAS-2436 - Commiting Pluggable Serialization into JBAS 4.0" (http://jira.jboss.com/jira/browse/JBAS-2436)

Brian:

"The values should be copied. Without them the Invocation API contract cannot be properly met (e.g. Invocation.getInvocationContext(), Invocation.getTransientValue()).

Maybe those methods are never called (except, I guess, now they are called in your tests ) but they are part of the API and properly supporting the API is worth the cost of a couple of assignment operations."
