Scenario:

• two applications are deployed:

• pa.war
• service.war

1) Start a process instance of a process which invokes a bean from pa.war => engine orchestrates context switch to pa.war
2) the bean looks up a Local EJB from service.war and invokes it => container performs context switch to service.war
3) the invoked EJB starts another process
4) this process invokes a Java Delegate implementation from pa.war

==> Problem: CNFException because the process engine does not perform the context switch back to the pa.war / does not detect that the container manipulated the thread context in steps 2-3
