I had the same problem using spring boot, I solve it injecting ResourceLoader, getting its class loader.

@Autowired
private ResourceLoader resourceLoader;

....
ClassLoader classLoader = resourceLoader.getClassLoader();
...


Proxy.newProxyInstance(
  classLoader, //for example...
  new Class < ? >[] {MyInterface.class},
  new InvocationHandler() {
  // (...)
});
