stackDepth
int stackDepth()Returns the stack depth at which this monitor was acquired by the owning thread. Returns -1 if the implementation cannot determine the stack depth (e.g., for monitors acquired by JNI MonitorEnter).- Returns:
- the stack depth at which this monitor was acquired by the owning thread.
- Throws:
InvalidStackFrameException
- if the associated stack frame has become invalid. Once the frame's thread is resumed, the stack frame is no longer valid.- See Also:

thread
ThreadReference thread()Returns aThreadReference
object for the thread that owns the monitor.- Returns:
- a
ThreadReference
object for the thread that owns the monitor. - Throws:
InvalidStackFrameException
