Edit: all the problem above can be avoided by creating an executable jar with built-in jvm arguments. Once created, I can bundle it into a .app using appbundler. How can I integrate VM arguments into my executable .jar?
I've got an executable jar that I've got to bundle into a .app using appbundler by Oracle (to make it work on OS X). My jar works perfectly on OS X if i launch it from the terminal using java -XstartOnFirstThread -jar PhotoSelector.jar. Due to SWT (packaged in my executable jar) and Cocoa restrictions, I've got to set -XstartOnFirstThread as a java argument. The problem is that I don't know how to configure properly Eclipse (Ant!) to set that double click to .app will execute my app using -XstartOnFirstThread argument. These are my XML files:
Build.xml

So, my questions are:
- How to pass -XstartOnFirstThread to .app by default when double clicking?
- Wich targets I've got to select in eclipse ant tool to export my .app correctly?
Right now my .app is created but it closes immediately. I use appbundler because Jar Bundler doesn't support Java 1.7 (widely used in my project). Thank you!
