ServiceRegistryImpl is registered twice: once as a singleton and once as a service tracker
------------------------------------------------------------------------------------------

                 Key: JBRULES-2682
                 URL: https://jira.jboss.org/browse/JBRULES-2682
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-api
    Affects Versions: 5.2.0.M1
            Reporter: Antoine Toulme
            Assignee: Mark Proctor
             Fix For: FUTURE
         Attachments: ServiceRegistryImpl.patch

This bug occurs when using Drools inside an OSGi environment. The ServiceRegistryImpl is instantiated instead of using the instance singleton, which leads to having objects being registered against the wrong ServiceRegistry. The OSGi class loader won't let the default instantiator work, as the classes are part of a different bundle. As a result, the configuration of the knowledge base fails.

The patch attached fixes this problem, it is a one liner.
