How is thread getting killed inside try-catch block?

Question

I have one thread-1 that is infinitely running.

public void run(){
    while (true)
    {
      try
      {
        serverSocket.receive(packet);
        processReceivedPacket();
      }
      catch (Exception x){ }
    }
}

I have 10 other threads. After running this application for a while I can see that my application is running but this thread-1 is not running anymore.

jstack -l pid >> stack.txt

When I take a stack of the process I can see the other threads, not this thread-1.

Is it possible that JVM is killing this thread even after try-catch block?

If the thread is not dead then how to find out which line the thread-1 is currently executing. Jstack is not working. In the Jstack file, there is no information for this thread-1.
