    logs uncaught errors in AbstractServer (#6161)
    
    While working #6139 caused an exception in the servers main threads that
    also initiated a halt.  The halt seemed to preempt java from printing
    exceptions from the main thread, so the exception was never seen.  This
    made tracking the bug down more difficult.
