7993	"Web Start version won't launch: ""Unable to launch the application: Unsigned application requesting unrestricted access to system"""	pbb	pbb	"Hi,

All of a sudden, I am not able to launch the Web Start version (JNLP) of JOSM anymore.

I receive a dialog window titled ""Application Error"" with the headline ""Unable to launch the application.""

There is a Details button, clicking this opens another window with the text ""Error: Unsigned application requesting unrestricted access to system / Unsigned resource: http://josm.openstreetmap.de/download/josm-tested.jar"".

There is also a textfield with two tabs Launch File and Exception. Both contain more or less the same info, the Exception tab containing a bit more:

This may be caused by a policy change (it's my office computer, connected to a domain).

Luckily, the download version still seems to work."	defect	closed	normal		Core Webstart		worksforme
