Heh, that /is/ silly.
The javadoc for HttpServlet states that, by implementing doGet, you
enable the GET method for your servlet. By calling the superclass's
doGet method, you get the default implementation, which is to /not/
support GET (sorry, I can't find the source for HttpServlet quite yet,
so you'll have to read bytecode):
protected void doGet(javax.servlet.http.HttpServletRequest,
javax.servlet.http.HttpServletResponse) throws
javax.servlet.ServletException, java.io.IOException;
Code:
0: aload_1
1: invokeinterface #7, 1; //InterfaceMethod
javax/servlet/http/HttpServletRequest.getProtocol:()Ljava/lang/String;
6: astore_3
7: getstatic #8; //Field lStrings:Ljava/util/ResourceBundle;
10: ldc #9; //String http.method_get_not_supported
12: invokevirtual #10; //Method
java/util/ResourceBundle.getString:(Ljava/lang/String;)Ljava/lang/String;
15: astore 4
17: aload_3
18: ldc #11; //String 1.1
20: invokevirtual #12; //Method
java/lang/String.endsWith:(Ljava/lang/String;)Z
23: ifeq 40
26: aload_2
27: sipush 405
30: aload 4
32: invokeinterface #13, 3; //InterfaceMethod
javax/servlet/http/HttpServletResponse.sendError:(ILjava/lang/String;)V
37: goto 51
40: aload_2
41: sipush 400
44: aload 4
46: invokeinterface #13, 3; //InterfaceMethod
javax/servlet/http/HttpServletResponse.sendError:(ILjava/lang/String;)V
51: return

Your servlet is still running, but the response has already been sent to
the client saying "405 Unsupported Protocol".
I'm actually a little surprised that you didn't get a response already
committed" error or something like that when you tried to write to the
output stream.
Try removing the call to super.doGet().
