Subject: Java-based app bundle with minimum os version simply crashes on
	machine with lower os version
Message-ID: <CAEnqZEV2MOxy1RuLKUVir_4yZ33jVJ3uySJB=w7vwBXpiuASfg@mail.gmail.com>

Hi,

I wanted to require a minimum os version for our app bundle and was
disappointed to realize that when I use the LSMinimumSystemVersion key for
that in Info.plist that the behaviour of the application when started on an
OS with a lower version is simply to crash (I tested by making the min
version artificially high, the app normally does run on that machine).
There is an explanatory text in the crash log, should the user choose to
look at it but that is obviously not what I want to have as behaviour of a
commercial application. Do I have any other choice but to program this in
Java now?

Thanks in advance for any hints,

Robert

Wouldn?t this be all OS and nothing to do with java?

I think it would be part of the launcher binary that is in the app bundle.

I would think so and I would have expected something like a system dialog
displaying a message like "this application needs at least OS 10.9.0 to
run, exiting.." and then the startup being aborted. Does anyone know if
that's a bug or if it's just a case of nobody having taken the time to
write code for that system dialog and having put an assert in there instead?
