[jira] Created: (FELIX-1783) Eliminate contention on ServiceRegistry.getServiceReferences(String, Filter)

Eliminate contention on ServiceRegistry.getServiceReferences(String, Filter)
----------------------------------------------------------------------------

                 Key: FELIX-1783
                 URL: https://issues.apache.org/jira/browse/FELIX-1783
             Project: Felix
          Issue Type: Improvement
          Components: Framework
    Affects Versions: felix-2.0.1
            Reporter: Karl Pauls
            Assignee: Karl Pauls
             Fix For: felix-2.2.0


FELIX-1746 uncovered some contention inside the service registry. It provides a patch based on a COW map implementation. However, for now we are going with a patch that removes the contention by doing some more copying and less locking. This is a short-term solution and we need to go back to FELIX-1746 and see where and how we can make use of the COW map in other places too as well as in this one.
