The JPAInjectedFailureTestCase that is part of the transaction testsuite is failing in the newest release. It ends up with transactions in  unexpected heuristit status after failover injection.

Description of the test: The test case injects some failures to the process of two-phase-commit protocol. Which means that we intentionally adds some exception being thrown in the 2PC methods and we check the results at the end.
Test flow:
      1) prepare jdbc xa resource
      2) prepare test xa resource
      3) commit jdbc xa resource
      4) RuntimeException is thrown
      5) commit test xa resource
      6) do recovery
      7) as the jdbc xa resource was already prepared the recovery will
         do commit on the prepare resource

Expected failures:
      MySQL
        com.mysql.jdbc.jdbc2.optional.MysqlXAException: XAER_RMFAIL: The command cannot be executed when global transaction is in the PREPARED state.
