Bug Description:
Although we don't test this particular site with our Mac frequently, we believe that it has worked recently. Gatekeeper now prohibits its execution.

"xxx.jnlp can't be opened because it is from an unidentified developer."

Works fine on Windows.

NOTICE:
[...]
Any software or app not signed for these versions of Mac OS X will not be allowed to run by the Gatekeeper feature in its default setting (see screenshot below). Gatekeeper will prevent application installers from running until you obtain a version of the software that contains an updated digital signature or alter the Gatekeeper setting to 'Anywhere'.

The changes Apple is making are covered in Apple Technical Note 2206.



Steps to Reproduce (be specific):

Launch the application with webstart

Setting the GateKeeper setting to allow from "Anywhere" allows the program to run
