> The invoke method would go like this:
> {code:title=TCCLServiceDependencyImpl.java|borderStyle=solid}
>         @Override
> 	@SuppressWarnings("rawtypes")
> 	public void invoke(
> 		Object[] callbackInstances, DependencyService dependencyService,
>                 ServiceReference reference, Object service, String name) {
> 		Bundle bundle = reference.getBundle();
> 		BundleWiring bundleWiring = bundle.adapt(BundleWiring.class);
> 		ClassLoader bundleClassLoader = bundleWiring.getClassLoader();
> 		Thread currentThread = Thread.currentThread();
> 		ClassLoader contextClassLoader = currentThread.getContextClassLoader();
> 		currentThread.setContextClassLoader(bundleClassLoader);
> 		try {
> 			super.invoke(
> 				callbackInstances, dependencyService, reference, service, name);
> 		}
> 		finally {
> 			currentThread.setContextClassLoader(contextClassLoader);
> 		}
> 	}
> {code}
> If you think this is useful I can provide a patch. Which version and which repo should I use for it?
