I created a multi-threaded application where each thread posts an XML request to an HTTP server. I place each thread in a ThreadGroup. I noticed that when I poll the number of active threads in the ThreadGroup by using the actievCount() method, I always have one thread active. When I debug the thread and print the contents of the ThreadGroup at 500 ms intervals using the list() method I see my threads but after all my threads are finished and die, I see the following:
This thread never dies. Does anyone know what this thread is and how it got placed in the ThreadGroup? This thread is not present when I have my threads still active. I am using JDK 1.3.1. Any help would be appreciated.
