Description

In case of multimodule deployment, LazyInitProxyFactory#createProxy() ends up with NoClassDefFound error while trying to wrap a class which is being injected into a Wickets component.

			CGLibInterceptor handler = new CGLibInterceptor(type, locator);

			Enhancer e = new Enhancer();
			e.setInterfaces(new Class[] { Serializable.class, ILazyInitProxy.class,
					IWriteReplace.class });
			e.setSuperclass(type);
			e.setCallback(handler);
			e.setNamingPolicy(new DefaultNamingPolicy()
			{
				@Override
				public String getClassName(final String prefix, final String source,
					final Object key, final Predicate names)
				{
					return super.getClassName("WICKET_" + prefix, source, key, names);
				}
			});

			return e.create();

As we can see, Enhancer is not configured with an context-relative classloader. This is the root of the issue.
