What we're referring to is to remove sun.management.Hotspot*, the
internal MBeans which are never exposed and registered in the platform
MBeanServer. The internal metrics in HotSpot VM should be retained as
they are exposed through other ways like jstat, GC logs, etc.

Hello,
We switched the Jetty builds to Java 21 a while ago, and they randomly
fail with a hard deadlock during class initialization.
We tried to understand if we were doing something wrong, but the code
compiles fine, and at first glance there seems to be nothing wrong
with it, but it may well

Hi,
It would be a shame to lose these metrics because many of them have been very
useful over time and some would be even more useful with some modifications.
