How could it be not an improvement to save ~600 bytes of native memory per class? Sorry, but I start to have real problems to follow this discussion. First you don't want to change strongly linked Hidden Classes to weakly linked ones **because** of the native memory overhead and then you say that a more sophisticated implementation which will eliminate this overhead would **not** be an improvement. I'm puzzled. ------------- PR: https://git.openjdk.org/jdk/pull/12493
