has no effect on the result returned by the

method.
Classes are only transformed once within the same classloading

a part of.transformer

. None of the classes loaded
by this class loader will be visible to application

the scope of the PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)
call.
