Memory leaks for 2 phase commit readonly transaction
----------------------------------------------------

                 Key: ISPN-845
                 URL: https://issues.jboss.org/browse/ISPN-845
             Project: Infinispan
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 4.2.0.Final
            Reporter: Changgeng Li
            Assignee: Manik Surtani
            Priority: Blocker


If  a method that is declared with read only transactional attribute by '@Transactional(readOnly=true)', using jboss transaction manager, and inside this method two caches are visited, there will be memory leak after the method is invoked.

The leak happens in TransactionTable instances, localTransactions map and xid2LocalTx map. It seems the commit phrase is skipped and the cleanup method is failed to be called to clean entries in these two maps.

My test shows if the transaction just enlists one cache, there won't be any problems, but I haven't test whether using DummyTransactionManagerLookup will resolve this.

This bug break our system where readOnly DAO methods are heavily used with infinispan as hibernate second level cache.
