             Summary: DUCC Service Manager - intermittent crash on startup loading service
registrations.
                 Key: UIMA-2708
                 URL: https://issues.apache.org/jira/browse/UIMA-2708
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


During SM init, as well as during registration, SM does a topological sort to detect and reject
circular references.  The code needs to account for independent services which might be implicit,
or submitted in the future (i.e. references to currently unregistered services) and ignore
them in the topo sort.  This is ok because if they're not registered, they're not in a cycle.
 If they are registered later, the topo sort will occur as part of registration and they'll
then be included, so all is well.
