------------------------------------

             Summary: DUCC SM race: rapid unregister/deregister can corrupt state.
                 Key: UIMA-4587
                 URL: https://issues.apache.org/jira/browse/UIMA-4587
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
    Affects Versions: 2.0.0-Ducc
            Reporter: Jim Challenger
            Assignee: Jim Challenger


If an unregister followed by a very quick register for a service with the same endpoint is
done, the internal tables managing these regs can get corrupted.  The problem appears to be
missing 'synchronized' around the CLI-based methods.
