             Summary: Improve namespace handling
                 Key: SLING-5534
                 URL: https://issues.apache.org/jira/browse/SLING-5534
             Project: Sling
          Issue Type: Improvement
          Components: JCR
            Reporter: Carsten Ziegeler
             Fix For: JCR Base 2.3.2


Right now the namespace handling support requries a proxy of the session object (in order to have namespace handling for impersonated session).
In addition for each new session, the mapping code is run, although it should only run once and register the namespaces in the registry.
This should improve performance as we don't have to run the namespace handling code for each and every session and get rid of the proxy.
The namespace registration itself gets a little more tricky, but basically we can directly change the registry whenever a bundle with a namespace header arrives. We just need to think about collition handling
