They'll still visit the class loader with the class. I'm still trying to work out how to describe this change in behavior for these tools and maybe have a CSR for it. There was only one test left that failed because of this change - was hoping some hprof test would fail so I could see the effect of that. I'm still working on this though, but I wanted to publicize the change first. ------------- PR Comment: https://git.openjdk.org/jdk/pull/32519#issuecomment-5452434006
