The JGSS component of OpenJDK ignores the value of javax.security.auth.useSubjectCredsOnly when using HTTP/SPNEGO authentication and always uses global credentials, see: https://bugs.openjdk.java.net/browse/JDK-6560359 This could cause global credentials to be unexpectedly used by an untrusted Java application. The fix adds new system property http.use.global.creds which, when set to false, prevents the use of global credentials.
