             Summary: Conditional Operation can fail erroneously during ST
                 Key: ISPN-3830
                 URL: https://issues.jboss.org/browse/ISPN-3830
             Project: Infinispan
          Issue Type: Bug
          Components: State transfer
            Reporter: William Burns
            Assignee: Mircea Markus


Currently the retry logic for commands is to only throw a OutdatedTopologyException when a command is successful.

This however can have the following issue. 

k1 owned by N1, N2 

# N3 updates k1 sending conditional command to N1 
# N1 receives command and starts running it (passes topology block)
# ST occurs causing N1 to no longer be an owner and removes k1 from it's data container.
# N1 runs optional command and it fails and thus doesn't throw OutdatedTopologyException
# N3 gets response that command failed, but it could have worked had it gone to a real owner.
