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.
