             Summary: Return value of Cache.remove(key) not consistent in transactional context
                 Key: ISPN-2164
                 URL: https://issues.jboss.org/browse/ISPN-2164
             Project: Infinispan
          Issue Type: Bug
          Components: Core API, Transactions
    Affects Versions: 5.1.5.FINAL
            Reporter: Carsten Lohmann
            Assignee: Mircea Markus


I have a scenario where multiple threads attempt to remove the same key concurrently via "cache.remove(key)" (each thread having explicitly started a transaction).
I expect only one thread to succeed, ie. only one invocation of "cache.remove(key)" to return a non-null value.
But that is not the case, the return value of "cache.remove(key)" is non-null for more than one thread.

In that sense, "cache.remove(key)" seems to behave differently from "cache.remove(key, value)".

The bug can be reproduced by using a test analogous to the one in "DummyTxTest" (ISPN-2077), but using "cache.remove(key)" instead of "cache.remove(key, value)".
