Jonathan Halliday commented on JBTM-443:
----------------------------------------
working as expected.
LastResourceRecord.doSave is AbstractRecord.doSave i.e. false, so no resource record written for the 1x RR + 1x LRR case
in 2x LLR + 0x RR tx then all records have doSave == false, so no tx log written.
> check LastResource logging and recovery

> Where transactions contain LastResource, they may not be fully recoverable. Check if LastResource records are written to the log and if so, what happens to them during recovery.
> Optimise the case where a tx contains multiple last resources, as we need to write a log for such a tx only if it also contains real resources. The case where the tx only has a single resource enlisted is irrelevant as the onePhaseCommit optimization already skips logging.
