Michael,
There is an issue in the tunneling/Http retry code whereby a proxy
requiring authentication, if it gives a bad response after the initial
407, may cause the HTTPClient to perform recursive calls to parseHTTP
until StackOverFlow. The reason is obvious when you look at the "try
once more" in HttpClient (webrev).
This fix required some cleaned in HttpURLConnection, and partially
removes a previous fix, CR 6216082. I verified that this part of the
change for 6216082 is no longer required, and confirmed this by running
the test that was added as part of 6216082.
