Issue:
Taking a heap dump is a stop the world event. Garbage collection events can
provide heap utilization information only after a cycle completes. We've found
that detailed heap occupancy data (such as heap inspections provide) are too
expensive to use for production monitoring. Similarly, we find

When the VM is run with `-XX:UseBranchProtection=pac-ret` on a supported CPU,
the upper bits of the saved link register contain a "pointer authentication
code" which must be checked and removed by a special instruction before a
function returns. The serviceability agent is unaware of this and
