ClassLoader getNewTempClassLoader()

Return a new instance of a ClassLoader that the provider may use to temporarily load any classes, resources, or open URLs. The scope and classpath of this loader is exactly the same as that of the loader returned by PersistenceUnitInfo.getClassLoader.

The provider may only use this ClassLoader within the scope of the PersistenceProvider.createContainerEntityManagerFactory call.
