Getting implemented interfaces from the proxy

You normally crate a proxy using

val proxy = Proxy.newProxyInstance(ClassLoader, Class<?>[] interfaces, handler)

I am interested in the second parameter because I save created proxies in a list and I want to recreate the proxy with the same interfaces later on. Should I memorize interface classes along with the proxy list or there is a way to map proxy to its implementing interfaces, likewise Proxy.getInvocationHandler(proxy) does for handlers?

proxy.getClass.getInterfaces, since getInterfaces returns all implemented interfaces and the proxy class implements exactly the interfaces passed to newInstance.
