org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.predeploy()
Perform any steps necessary prior to actual deployment. This includes any steps in the session creation that do not require the real loaded domain classes. The first call to this method caches persistenceUnitInfo which is reused in the following calls. Note that in JSE case factoryCount is NOT incremented on the very first call (by JavaSECMPInitializer.callPredeploy, typically in preMain). That provides 1 to 1 correspondence between factoryCount and the number of open factories. In case factoryCount > 0 the method just increments factoryCount. factory == 0 triggers creation of a new session. This method and undeploy - the only methods altering factoryCount - should be synchronized. @return A transformer (which may be null) that should be plugged into the properclassloader to allow classes to be transformed as they get loaded. @see #deploy(ClassLoader,Map)

                    // Persistence unit cannot be used standalone (only as a composite member).
                    // Still the factory will be created but attempt to createEntityManager would cause an exception. 
                    emSetupImpl = new EntityManagerSetupImpl(puName, puName);
                    // Predeploy assigns puInfo and does not do anything else.
                    // The session is not created, no need to add emSetupImpl to the global map.
                    emSetupImpl.predeploy(puInfo, properties);
