             Summary: PutMapCommand throws a NullPointerException in Distributed Mode
                 Key: ISPN-2006
                 URL: https://issues.jboss.org/browse/ISPN-2006
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Cache
    Affects Versions: 5.1.4.CR1
         Environment: Infinispan 5.2.0-SNAPSHOT
            Reporter: Pedro Ruivo
            Assignee: Manik Surtani


I've spotted a bug in PutMapCommand. When the keys in the Command touches in multiple nodes, the remote nodes (nodes that didn't created 
the command) can throw the exception [1] when executing the perform() method. I'm using a transactional cache.

The test case in [2] reproduces the bug.

[1] Exception:
