It does seem that being able to tell whether a java object monitor is

Perhaps it would be useful to be able to expose a java object monitor
as an instance of Lock?
Lock lk = Lock.ofMonitor(object)
if (lk.tryLock()) {

}
Such a method feels like it would be a useful missing link between
synchronized and locks.
I don't think this is workable. Exposing a monitor as Lock would allow
you to break the guarantees/requirements involving balanced-locking for
monitors.
The JNI APIs also allow this, do they not?
