FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7600]

A DESCRIPTION OF THE PROBLEM :
Basic authorization fails when using HttpUrlConnection on Windows 7. Please note that the same code works on Linux and OSX. A packet trace reveals that the http header "Authorization" only has a "\r" carriage return and no "\n" line feed. Thus the server does not recognize the auth header and fails with a http 401.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided sample code on windows 7 (32 -bit), accessing a server that has basic authorization setup, using a valid user name and password.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A proper http get request should be created and it should authenticate properly.
ACTUAL -
the server returns a 401 and an exception is thrown

ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost:8080
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
at sorenson.threesixty.test.HttpUrlConnectionBugTest.main(HttpUrlConnectionBugTest.java:42)


REPRODUCIBILITY :
This bug can be reproduced always.
