I can't get anywhere close to a working admin console anymore..from any of my laptops/desktop machines.
Either the web browser pops up the annoying "Java 2+ Required" (which i've installed java multiple times now), or the admin.jnlp method will pop up long enough to let me log in.. quickly display an error message (too quick to read) and then crash.
(for the love of all things holy: please move away from "java"... anytime there's an update, everything breaks, and I'm stuck troubleshooting again)
