Thanks for your explanation. I understood the problem - for example, initial stubs could have "forward exception entry" and "call stub entry". I think we can use `StubCodeDesc::desc_for()` to check/find `StubCodeDesc` for arbitrary address. It could be more simple your change. For the naming, I'm ok to use the space in the label. I just want to comment you have to care if you want to use `::` in the label. ------------- PR Review: https://git.openjdk.org/jdk/pull/31007#pullrequestreview-4353665607
