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

              Status: Pull Request Sent  (was: Open)
    Git Pull Request: https://github.com/infinispan/infinispan/pull/1671


Copy the address cache into a regular map before generating the
topology response, to protect from changes from other threads.

Send topology responses even if not all CH members are in the
address cache. This allows the client to remove leaving HotRod
servers from its CH.
