Right, there's no such guarantee/requirement.  JVMS mentions that

And this proposal would make it impossible to enforce balanced locking.

When we defined the Lock API we thought about whether/how Locks and built-in monitors might interact and the decision was to keep them completely distinct.

I don't think this is workable. Exposing a monitor as Lock would allow
you to break the guarantees/requirements involving balanced-locking for

Where are these guarantees/requirements documented?
