> The addAll method suspends a possible transaction, and is invoked without
> any transaction. It in turn calls add, which always creates a new
> transaction, in a loop. Add uses an EntityManager to persist, and the call
> fails with a TransactionRequiredException. Why is that, shouldn't the add
> method start and finish the transaction for every call?
> (I do want to call the persist method in a new transaction every time, this
> is a very specific part of the app and this cannot change.)
