Is there a way to set the -mx memory use parameter?
My application needs more memory than the default, and it
would be a lot cleaner if it could be specified in the .jar
rather than having to distribute a shell file to launch the program.

There is no way to do this in the JAR or its manifest. I find it one of
the more annoying shortcomings of double-clicked jars.

This seems like one of those it would be easy enough to come up with on your own java launcher.
The two ways to do it would seem to be either...
Have the double-clicked jar Runtime launch with the parameters you want parameter list/plist or in some other way specified to use in launching the java Runtime process. Not that I want to get immediately back into a Runtime discussion. In this though I still think java running java is not the preferred way to go.
The preferred way would probably be the same way Apple does. Have a little native launcher stub that reads a parameter list and launches the jvm. I haven't looked at it yet but I think a sample is provided to do this. You might need separate cross-platform executables although I thought 'fat' options were somehow supported?
