ThreadMon provides a thread status monitor for Java virtual machines. It runs as an applet in its own frame, and will survive between browser page changes. It allows the user to change the priority of threads in the Java virtual machine, and to suspend, resume and stop threads, subject to any security restrictions imposed by the virtual machine.
These features give you more than enough rope to hang yourself, so be careful when manipulating threads in the system or main groups. In particular, if you suspend the thread that processes input events (AWT-Input in Netscape 3.0), that'll pretty much make it impossible for Java to ever deal with you again.
ThreadMon samples the states of threads only once a second or so. Very short-lived threads may never appear in the thread display.
