> The java client rejects all messages prior to rollback. This should not cause a problem with any compliant broker as the effect of the reject will be rolled back, however it should not be necessary. Commenting out these rejects causes test failures. This may indicate that the broker somehow depends on this behavior in order to correctly rollback a session. If so the broker will have trouble interoperating with other conformant clients. Additionally the java client appears to hold back all message acknowledgments until the transaction commits. I'm guessing this is to avoid first acknowledging and then rejecting the same message when a rollback occurs. If the reject is removed, this behavior could probably be simplified.
