which is then caught and handled as a 'normal' XAException.

which results in us considering the transaction as complete -
thus the transaction is lost.

which was caught and handled as a 'normal' XAException.

more
?
which resulted in the transaction service considering the
transaction to be unrecoverable. As a result, the transaction
was forgotten which is the correct action for XAER_RMERR.

Problem conclusion

The transaction service has been changed so that exceptions
thrown during reconnectRM will result in an XAException being
created with error code XAER_RMFAIL, which will mean that the
transaction will be kept by the transaction service for retry.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.0.2.39, 6.1.0.29 and 7.0.0.7.  Please refer to the
