12373	Cannot start JOSM on OS X 10.10.5	anonymous	team	"I am on OS X 10.10.5 and downloaded JOSM here https://josm.openstreetmap.de (Download josm-tested.jar (version 9329)).
I double clicked on the .jar file and got the message that it cannot be opened. I read in the wiki that Java 6 or later is required. I am on Java 8.
I tried from terminal with java -jar josm-tested.jar - no success neither. I get sort of a listing in there...

Then I downloaded JOSM from here https://josm.openstreetmap.de/wiki/De%3ADownload (package.zip for Mac OS X) and double clicked on the Icon which looks like a map. The app seems to start (it appears in the doc) and then it closes down without any warning. I do not even see a window popping up or something. 
I turned of Gatekeeper, restarted the computer. Nothing changes. 
Any ideas?"	defect	closed	normal		Core		invalid	josm, osx, mac, java, problem
