ThreadInfo more info on blocking threads

[John Sutt]

Dear all,

I know how I can use a ThreadMXBean to get a ThreadInfo object about a thread in which I can find:
- a block counter (the number of object.wait() calls), and
- the blocked time (the time spend being blocked).

But can anybody tell me how to, e.g. install an agent, that can tell me the exact objects on which the threads are blocked? It seems this might be possible somehow.

Thanks in advance,
John.
