> The {{JobManager}} shuts down its {{ExecutionService}} when the actor is stopped. This causes the problem that the execution service which is used to run future callbacks is finished before the actor has completely terminated. Due to this there might be rpc answers which cause another {{Runnable}} to be submitted to the {{ExecutionService}}. This causes {{RejectedExecutionExceptions}} to be thrown. 
> The underlying problem is that the {{JobManager}} should not stop the {{ExecutionService}} before the actor has been terminated. This will be changed in Flip-6 anyway. In the meantime to suppress these exceptions, it will be checked whether the {{ExecutionService}} has been shut down and only if not, exceptions will be logged.
