 I have a process with two workitems in parallel.
 In executeWorkItem() I start a callable and execute completeWorkItem from a worker thread. When the flow runns for a while it blocks randomly. It seems the completeWorkItem() is not threadsafe and if different threads call it concurrently sometimes the acknowledging of the workitem gets lost.
 If I warp the ksession in a object and synchronize all calls it runns fine.
 I is told to do it this way in chapter of the manual. Isn't the completeWorkItem call not supposed to be threadsafe?
