org.eclipse.persistence.internal.helper.JPAClassLoaderHolder
INTERNAL: This class is a composite object containing the classLoader and a flag that is true if the classLoader returned is temporary.
JIRA EJBTHREE-572 requires that we use the real classLoader in place of the getNewTempClassLoader(). The override code should stay in place until the UCL3 loader does not throw a NPE on loadClass() @return ClassLoaderHolder - may be a temporary classLoader

            // Another workaround would be increasing Permanent Generation Heap size by adding VM argument -XX:MaxPermSize=256m. 
            if(!this.isInContainerMode && state==STATE_UNDEPLOYED) {
                privateClassLoader = realClassLoader;
            } else {
                // Get the temporary classLoader based on the platform
                JPAClassLoaderHolder privateClassLoaderHolder = session.getServerPlatform().getNewTempClassLoader(info);
                privateClassLoader = privateClassLoaderHolder.getClassLoader();
                // Bug 229634: If we switched to using the non-temporary classLoader then disable weaving
                if(!privateClassLoaderHolder.isTempClassLoader()) {
                    // Disable dynamic weaving for the duration of this predeploy()
                    enableWeaving = Boolean.FALSE;
