This new version does contain the fix for this bug: "HttpURLConnection sets Content-Type to application/x-www-form-urlencoded" http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6369510
This was already fixed in JDK 6.0 but not in 5.0 and was causing trouble with the Amazon Web services authentication scheme. See release notes: http://java.sun.com/j2se/1.5.0/ReleaseNotes.html#150_10 Best regards, Jerome
