When running an app (SWT based) from the JavaAppLauncher project, and using the StartOnFirstThread in the info.plist, I get the following error when trying the access AWT:

2012-01-23 22:11:27.102 MyCoolApp[11728:707] Cocoa AWT: Apple AWT Java VM was loaded on first thread – can't start AWT. (

JavaAppLauncherFailure CallStaticVoidMethod() threw an exception

In my JavaAppLauncher project, I've bundled a JRE (java.runtime.version=1.7.0-u4-b225-20120121).

I've attached the Java class I'm using as a test. Since MACOSX_PORT-784 was resolved, I can run this class using a JDK/JRE from the command line. However, with this class as the main class in the JavaAppLauncher project, I get the above exception.

Please let me know if you need more details.
