Currently there is a known intermittent failure related to:
java.lang.LinkageError: loader constraints violated when linking javax/servlet/http/HttpServletRequest class
(an issue tracker issue exists already) and we are working on it to resolve.
The old glassfish-v3 (for build, QL and publishing) job will be removed / retired.
(Admin Console QL is fixed now. But you still see the problem to due to the above known issue)
