Message Title

Suggested approach of using

entity = entityManager.getReference(getType(), entity.getId());

can't be used because our entity is a generic object, so no

getId

can be invoked unless forcing a specific base class.

Using the following approach:

final Object entityId = entityManager.getEntityManagerFactory().getPersistenceUnitUtil().getIdentifier(entity);

entity = entityManager.getReference(getType(), entityId);
