With this change: catch (RuntimeException e) | { | if (!transactedOrClientAck) | { | try | { | | consumer.acknowledge(jbm.getCoreMessage(), false); | | session.getCoreSession().rollback(); | | session.setRecoverCalled(true); | } | catch (Exception e2) | { | log.error("Failed to recover session", e2); | } | } | } | the message would be sent to the ACK list on the transaction before the rollback, so the counter would be incremented.
