I haven't tried your changes but I remember needing to change this test when doing experimental changes in this area.

Oh, so that test checks the owned monitors are in frames at particular stack depths! So my previous PR breaks that test because it makes a delegated call to `sleep` in `java.lang.Thread`: all actual offsets are off by one. New PR drops that delegation and the entirety of `vmTestbase/nsk/jdwp/ThreadReference` now passes.
