Data gravitation prefers exception response over valid gravitation
------------------------------------------------------------------

                 Key: JBCACHE-1528
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1528
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Buddy Replication
    Affects Versions: 3.1.0.GA
            Reporter: Brian Stansberry
            Assignee: Manik Surtani

A web request that performed a data gravitation for the session failed because one node returned an ISE while another returned the data. The ISE should have been ignored and the returned data used.

The first log message below shows what was returned from the gravitation RPC; the second indicates that the ISE propagated.
