Hmm ... honestly I do not know. Why does creating the mappings not work
in a a transaction?

The "..SynchronizeMappings" should be used outside JTA transactions
using auto commit. How could this ever work with JPA Blueprint then?

This is decided by Aries JPA. If you use transaction-type="JTA"
then the jta-datasource is used else the non-jta-datasource.

I think the important question is: _Who_ determines whether to
use the <jta-datasource> or the <non-jta-datasource>?
The follow-up question would be: _What criteria_ is being used to
choose between them?
