My thread TP-Processor27
is waiting, tells me a thread dump.
Usually WAITING (on object monitor)
lines are immediately followed by a waiting on <0x09c34480>
or similar line. But not in the dump below. In such cases, can I know on which id is the wait?

It seems that I saw a problem where there is actually no problem.
