No, it will not perform a commit.

It will not perform a commit since it will do it when the method
_that_started_the_transaction_ ends. And it is the method in Session EJB A (with
REQUIRES_NEW attribute) that started the transaction. Entity EJB B (with
REQUIRED attribute) will be included into this tx and not start a new one. But,
if Entity EJB B would have REQUIRES_NEW than the tx from Session EJB A would be
halted, a new one would be started fo Entity EJB B and that would be commited
when Entity EJB B method is finished. Tx from Session EJB A would then be
continued when returned.
