[infinispan-issues] [JBoss JIRA] Commented: (ISPN-845) Memory leaks for 2 phase commit readonly transaction

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 Fix For: 4.2.1.Final Attachments: infinispan.log 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.
