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

             Summary: stopped services still appear as available to clients
                 Key: DOSGI-177
                 URL: https://issues.apache.org/jira/browse/DOSGI-177
             Project: CXF Distributed OSGi
          Issue Type: Bug
          Components: DSW
    Affects Versions: 1.5
            Reporter: Amichai Rothman
         Attachments: fix_services_not_removed.diff

Sometimes TopologyManagerImport receives more than one endpointAdded event for 
the same endpoint and filter. Currently this causes it to add the endpoint 
multiple times to an internal list. However when the endpoint is removed, only 
one endpointRemoved event is triggered, one instance is removed from the list, 
and the other copies remain. The rest of the code treats this as the endpoint 
still being available, which is what the clients see as well (the import is 
never closed).

The patch simply adds a check so that the endpoint will not be added to the 
list if it already there. It also removes empty import lists when all imports 
are removed, preventing a leak.
