If a parallel flow involves colocated delegates the application hangs

                 Key: UIMA-1199
                 URL: https://issues.apache.org/jira/browse/UIMA-1199
             Project: UIMA
          Issue Type: Bug
          Components: Async Scaleout
    Affects Versions: 2.2.2
            Reporter: Burn Lewis
            Priority: Minor


Parallel flows can only run in parallel when the delegates are remote, but we 
should handle any colocated ones by running them sequentially in arbitrary 
order as synchronous UIMA does.  The spec says that the framework is not 
obliged to run them in parallel.  The alternative of rejecting the flow is 
undesirable as it can only be detected at run time since the flow controller 
may be user code.
