I think the change is not reflected in the database since the transaction associated
with 1) is the same as the one associated with method A (the Tx attribute is
TX_REQUIRED, not TX_REQUIRE_NEW...). Since that transaction rolls back, the database
does not keep the changes.
If you have an example that shows what you describe, you should ask an explanation
to the support for your server.
