In case of a shared ("transactional") EntityManager, this will be the raw EntityManager that is currently associated with the transaction. Outside of a transaction, an IllegalStateException will be thrown.

Returns:

the underlying raw EntityManager (never null)

Throws:

IllegalStateException - if no underlying EntityManager is available
