I have verified with the exact test program posted before applying the fix and I can confirm that scheduled delivery did work as expect if the sending session was non transactional, but did not work if the sending session was transactional. I have applied the fix, and can confirm it now works in both cases. I have also added test suite cases to cover this scenario. Fix will be in the next release, 1.4.0.CR1, due out next week.
