        Description

        FULL PRODUCT VERSION :
        java version "1.5.0_14"
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
        Java HotSpot(TM) Client VM (build 1.5.0_14-b03, mixed mode, sharing)

        ADDITIONAL OS VERSION INFORMATION :
        Microsoft Windows XP [Version 5.1.2600]

        A DESCRIPTION OF THE PROBLEM :
        When using HttpsUrlConnection in in conjunction with authenticated proxies, an endless recursion can occur when the proxy reacts unexpected. See coding below.

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run the coding supplied, the ProxyConnect class first.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        ProxyTest should fail cleanly.
        ACTUAL -
        StackOverFlowError

        REPRODUCIBILITY :
        This bug can be reproduced always.
