@Test
public void testPostDelegation() throws Exception {
    final VFSClassLoader parent = new VFSClassLoader(new FileObject[] { vfs.resolveFile(uri1) }, vfs);

    Class<?> pclass = parent.loadClass("test.HelloWorld");

        @Override/*from ww w  .ja  va 2 s .  c o m*/
        public ClassLoader getClassLoader() {
            return parent;
        }
    });

    cm.setContextConfig(new ContextsConfig() {
        @Override
