Hello, I work on Weld, context dependency injection framework. Long story short - we need to generate proxies for classes - bytecode which we then "register" with the class loader using java.lang.ClassLoader#defineClass.
Obviously, for this you need reflections - to load java.lang.ClassLoader, then to load the method itself, and most importantly, to make the method accessible cause it's `protected`. In JDK 9, this blows up as soon as you try to make the method accessible (invocation of setAccessible). Fair enough, but what is the "legitimate" alternative? I know I can --add-opens / --add-opens / --permit-illegal-access But all those just bypass the checks and don't really solve it. I am looking for an intended way to do such stuff. I am pretty sure there are many frameworks which need to do this in one way or the other. So far I have found workarounds which involve using `sun.misc.Unsafe` because there (for some reason) you are allowed to invoke setAccessible(). Is this the official intended backdoor? Because it sure does not look any safer/cleaner solution than the original one... Any thoughts appreciated Matej
