file.ClassLoader getClassLoader()
void addTransformer(ClassTransformer transformer)
getClassLoader()
method. The transformer has no effect on the result returned by the
getNewTempClassLoader()
method. Classes are only transformed once within the
same classloading scope, regardless of how many persistence units they may be a part of.transformer

. None of the classes loaded by this class
loader will be visible to application components. The provider may only use this ClassLoader within the
scope of the PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)
