uncaughtException method : problem

[Anshuman Acharya]

i can't understand the mechanics of it. Here's what i have found:
//starts here
public void uncaughtException(Thread t,Throwable e)
Called by the Java Virtual Machine when a thread in this thread group stops because of an uncaught exception.
The uncaughtException method of ThreadGroup does the following:
If this thread group has a parent thread group, the uncaughtException method of that parent is called with the same two arguments.
Otherwise, this method determines if the Throwable argument is an instance of ThreadDeath. If so, nothing special is done.
Otherwise, the Throwable's printStackTrace method is called to print a stack backtrace to the standard error stream.
//ends here
what is "ThreadDeath"?
could anyone explain me how this method works?
thanx

The genealogy of ThreadDeath is as follows:
Throwable implements java.io.Serializable
Error extends Throwable
ThreadDeath extends Error
Hope this helps
