I had reworked the patch, webrev is here: http://cr.openjdk.java.net/~shade/8016236/webrev.01/ The current webrev is here: http://cr.openjdk.java.net/~shade/8016236/webrev.02/ I'm just catching up on this thread, webrev.02 looks very good to me. I can sponsor it.

Thanks! I'll appreciate this.

One comment on ClassRepositoryHolder is that it's "yet another class" (we have a proliferation of holder classes since we started using this idiom). It makes me wonder if it might be better to move the constant to ClassRepository.

Ok, makes sense. I moved it to ClassRepository itself. Given we have the ClassRepository field in Class, the static initialization will be performed on the first class load. I have no problems having it public, since it is protected enough from the external modifications.

The new webrev is here: http://cr.openjdk.java.net/~shade/8016236/webrev.03/

Testing:
