the class EntityManagerSetupImpl method 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 proper
 *         classloader to allow classes to be transformed as they get loaded.
 * @see #deploy(ClassLoader, Map)
