Here is a simple example which reproduces this behaviour:

--------------->8---------------
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet
{
        public void destroy()
        {
                System.out.println("destroy()");

                synchronized (this)
                {
                        notifyAll();
                }
        }

        public void doGet(HttpServletRequest request, HttpServletResponse response)
        {
                System.out.println("doGet()");

                synchronized (this)
                {
                        try
                        {
                                wait();
                        }
                        catch (InterruptedException iex) {}
                }
        }
}
--------------->8---------------

In my eyes, this should work without any problems. (It does work just 
fine in Tomcat 3.2.2.)

Thanks!
