WLS Threads get stuck when exception "HeuristicHazard, (javax.transaction.xa.XAException: Two rollba

 Hi All,

We have just migrated WLS from 10.3 to 12.1.1.0.2 in our production environment. In our application we are using non-XA JDBC connection pool to emulate 2PC transactions. 

For details, please check link: http://docs.oracle.com/cd/E24329_01/web.1211/e24367/transactions.htm#i1211062 

When some exception comes then container starts rolling back the transaction as expected. The error in log file shows a Heuristic condition which is the expected behavior. However this rollback of current transaction is not successful and this causes the WLS threads in stuck state.
