Java application launched from PPC or bad stub

If you see this in your OSX Console log after trying to launch a Java application, the problem is obvious - you've been given an application with a Java stub launcher that cannot be run on your version of OSX.

The solution is a little less obvious.

$cp /System/Library/Frameworks/JavaVM.framework/Resources/MacOS/JavaApplicationStub 
 /Applications/<APPNAME>.app/Contents/MacOS


Some nasty log messages from trying to log an install4j based app that suffered this problem
