Although the new API is claimed to be supported starting with 10.7 only, it works fine on my 10.6.8 box as well (but prints out a warning about sending an unrecognized selector to an AWTWindow instance.)

A few points to consider:
* To protect against the unrecognized selector problem, you should test if the AWTWindow object -respondsToSelector:@selector(toggleFullScreen) before just calling it.
* Also, there is already API that calls -toggleFullScreen in the eAWT classes that you might not be aware of. You should probably test for interactions with that, since apps can opt their window into having a full screen widget icon and independently toggle fullscreen.
* In some cases, seeing the menubar is actually desirable, where as in the "exclusive" mode, it's probably not. Perhaps you could consult a client property on the window to determine if the menu bar should be hidden?
I like this overall solution, because it uses the native platform concept of full screen which doesn't trap the user from switching spaces like the Java SE 6 implementation did.
