AFAIK, the JavaApplicationStub is not a command, per se, while 'java_swt'
*IS* a command. Not all executables are commands. You cannot just blindly
swap one for the other in Info.plist or an app-bundle and have it work.

As I understand it, 'java_swt' is like the 'java' command, which is a
completely different animal than JavaApplicationStub, though both create a
JVM. However, I could be wrong, since I don't use Eclipse or SWT.

My suggestion is to read the documentation for 'java_swt' very carefully.
I would even go so far as to download Eclipse, look inside its app-bundle,
and follow that as a working example of a SWT app-bundle. If Eclipse is
able to build a valid Mac OS X app-bundle for a SWT program, then it would
seem to be the best reference on how to do so correctly.

That use of -Djava.library.path=... will not work. The VMOptions key is
only for -X options.

To predefine properties, put them in the Properties dictionary.

That one error alone almost certainly explains why your JNI libs aren't
being found.

The contents of Java app-bundles is described here:
<http://developer.apple.com/documentation/Java/Conceptual/ Java141Development/Dep
loyment_Options/chapter_4_section_3.html>

The Info.plist keys are detailed here:
<http://developer.apple.com/documentation/Java/Reference/ Java14JavaDict/KeysValu
es/chapter_3_section_1.html>

which is a page of this more extensive documentation:

...in fact eclipse
running on OSX wraps and calls java_swt. my hope was that i was not
going to have to do that.

If you're running a SWT program, then that's almost certainly what you have
to do. But you should do it exactly the same way that Eclipse itself does
it. There are probably smaller examples of working SWT-based app-bundles,
but I don't know what they might be since I don't use Eclipse or SWT.
