    The JPA spec doesn’t define such things and its up to the implementation to manage connections. When a transaction is active you’d be safe to assume the connection is the same until commit, for obvious reasons. Once the txn ends it may be handed back, or it may be held depending on implementation (and you don’t mention yours)
