SetExternalizer Cannot Properly Handle TreeSets Constructed With Comparator
---------------------------------------------------------------------------

                 Key: ISPN-1359
                 URL: https://issues.jboss.org/browse/ISPN-1359
             Project: Infinispan
          Issue Type: Bug
          Components: Marshalling
    Affects Versions: 5.0.0.FINAL
         Environment: OSX 10.7.1, System JDK
            Reporter: Ryan Scharer
            Assignee: Manik Surtani


TreeSets can be used to hold objects that don't implement Comparable, so long as you provide a Comparator during construction.  The current implementation of SetExternalizer doesn't support this pattern... trying to deserialize a TreeSet that holds objects that don't implement Comparable results in a ClassCastException.  This seriously reduces the flexibility of TreeSet.

JBoss Cache doesn't have this limitation, presumably because it delegates to native Java serialization.
