Not as many technologies as you think. I was able to narrow the problem down to 
only Jetty & JettyLauncher. Here's how to reproduce it:

test.jsp:
<% response.sendRedirect("https://localhost:8443/test2.jsp"); %>

test2.jsp:
<% response.sendRedirect("/test3.jsp"); %>

test3.jsp:
Can be whatever you like.

jetty.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure 1.1//EN" 
	"http://jetty.mortbay.org/configure_1_2.dtd">

Place all three JSPs in the app root, run Jetty using launcher and the attached 
XML file, and execute test.jsp. Presto!

Unfortunately, the network sniffers are not allowed on our network, so I won't 
be able to do that. In any case, I believe the problem is now sufficiently 
narrowed down to be posted as a bug.
