I am getting this again.
In the past, I was able to resolve by stopping/ starting adminserver, update JAVA, and use the latest JNLP, but not this time.
On the Mac OS server, version 10.8.5, running FMSA 12, current Java is 7 update 60. Below are some screens which I believe many will know
First launch admin-console-webstart.jnlp (at my macbook)
Click run at the next prompt
Ended in error
While reading the forum for solution, it was suggested to enter the host IP address as an exception site list under Javan control panel
Is this the only solution / "workaround" to it?
I forget to mention that there was an error trying to install the Java update. There is no clue what this error is. Despite this failure, the Java control panel still show the latest version is installed.
