java.util.concurrent.RejectedExecutionException can occur when ejb-client scoped context or remote-naming is used for calling remote EJBs as depending on the timing the executor could have been shutdown before some clean up tasks had run which could leak in the case of scoped context.
If a InitialContext use the remote-naming approach and close the Context after use a RejectedExcecutionException is thrown at the client side.
