The bug consists in a deadlock introduced by the fix for the bug JDK-8032832, which introduced locking on the thread context class loader in the method "sun.net.www.protocol.http.NegotiateAuthentication.isSupported(HttpCallerInfo)". The fix just fully reverts changes introduced by the fix for JDK-8032832.
