Hi Wolf,

That is one of the use cases. 

> That will not be true, it is possible to have multithread clients with AS7, but as I mentionend it is completly different in implmentation and use.

This why I opened this ticket. While the framework clearly allows for multiple targets and there is nothing to inhibit a multithreaded client, I am pointing out a race condition in the implementation with respect to static in EJBContext. Again, looking at the EJBInvocationHandler, you can clearly see that it is indirectly manipulating a static member by calling the requireCurrent(). Two threads in the EJBInvocationHandler doInvoke code can end up pointing to the wrong SELECTOR.
