Message Title

Did a quick test, the only ClassLoader issue that I have is the one in the org.hibernate.proxy.pojo.javassist.JavassistProxyFactory#buildJavassistProxyFactory.

One can workaround this issue by importing the org.hibernate.proxy and javassist.util.proxy packages in the bundle bundle containing the entity class.

I've also did a quick test changing the org.hibernate.proxy.pojo.javassist.JavassistProxyFactory#buildJavassistProxyFactory method to use a ClassLoader that aggregates two ClassLoaders (the Hibernate ClassLoader and the ClassLoader of the entity class). This resolves the issue and I don't see any ClassLoader issues.

	public static javassist.util.proxy.ProxyFactory buildJavassistProxyFactory(
			final Class persistentClass,
			final Class[] interfaces) {
		javassist.util.proxy.ProxyFactory factory = new javassist.util.proxy.ProxyFactory() {
			@Override
			protected ClassLoader getClassLoader() {
				final ClassLoader cl1 = persistentClass.getClassLoader();
				final ClassLoader cl2 = HibernateProxy.class.getClassLoader();
				return new ClassLoader() {
					@Override
					public Class<?> loadClass(String name) throws ClassNotFoundException {
						try {
							return cl1.loadClass(name);
						} catch (ClassNotFoundException cnfe) {
							return cl2.loadClass(name);
						}
					}
				};
			}
		};
		factory.setSuperclass( interfaces.length == 1 ? persistentClass : null );
		factory.setInterfaces( interfaces );
		factory.setFilter( FINALIZE_FILTER );
		return factory;
	}
