[Dan Berindei (JIRA)]

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

             Summary: Can't access a non-clustered cache via HotRod
                 Key: ISPN-2773
                 URL: https://issues.jboss.org/browse/ISPN-2773
             Project: Infinispan
          Issue Type: Bug
          Components: Server
    Affects Versions: 5.2.0.CR3
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Blocker
             Fix For: 5.2.0.Final


With the ISPN-2632 fix, we switched from using the JGroups view id as a HotRod topology id, to using the topology id of the cache being accessed.

If the cache isn't clustered, however, it doesn't have a RpcManager and attempting to read the cache's topology id results in a NullPointerException:
