Re: JAVA stops spawning (Thorbj?rn Ravn Andersen)

Thanks for your reply.  The source you reference states having the run() method 
terminate ends the thread.  In my run() method I loop until the request is 
finished, then it falls out of the loop and exits.  (I know it is out of the 
loop from my logger entries.)  After the loop I set a public  class flag that 
says the thread is done and the run() method ends.  It is my understanding that 
as long as there is a reference to it, the object is kept around.  My routine 
to 'null' the table entries looks for threads entries with this flag set on.  
(We are on JVM 1.4.2, so I can't use the new isDead call from 1.5.)  My table 
is limited to 64 entries, so I'm fairly confident that the threads are being 
'null'ed correctly, else the table would overflow.
