Comments
Fix Request: I would like to backport this change to openjdk 8u. It is part of the Oracle updates as well. The patch applies cleanly and the test passed for 10 iterations.

It's not failing in the expected place (the InputStream.read()) call. Instead, it's getting a Connection refused error from trying to connect to the server, which sounds more like a resource limitation on the system. It doesn't seem like a product bug, but the test might need to be updated to catch the connect exception. Will investigate further.
