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

             Summary: HotRod RemoteCache.keySet() results in server-side
ClassCastException on M/R task when using DIST Cache with compatibility-mode enabled.
                 Key: ISPN-3785
                 URL: https://issues.jboss.org/browse/ISPN-3785
             Project: Infinispan
          Issue Type: Bug
          Components: Core API, Distributed Execution and Map/Reduce, Remote protocols
    Affects Versions: 6.0.0.Final
         Environment: Mac OS-X 10.9, Oracle Hotspot 1.7.0_45
            Reporter: Duncan Doyle
            Assignee: Galder Zamarreño


When doing a HotRod RemoteCache.keySet(); call on a DIST Cache with <compatibility
enabled="true"/>, the BulkUtil.getAllKeys() M/R task on the server-side will
throw a ClassCastException:
