org.apache.openjpa.lib.util.MultiClassLoader
Class loader type that can be configured to delegate to multiple internal class loaders. The {@link #THREAD_LOADER} constant is a marker that will be replacedwith the context loader of the current thread. @author Abe White

        // If pooling EMFs, this method may be invoked more than once. Only perform this work once.
        if (_preloadComplete == true) {
            return;

        MultiClassLoader multi = AccessController.doPrivileged(J2DoPrivHelper.newMultiClassLoaderAction());

        multi.addClassLoader(AccessController.doPrivileged(J2DoPrivHelper
            .getClassLoaderAction(MetaDataRepository.class)));
