Just dis-information there.
It is a complete VM, it will run any JDK 1.3 code you throw at it.
Right now I'm attempting to work my way around the Tao Group defending the javax.swing package space from borders.
I'm probably going to have to re-package the GNU code into something like javai.swing instead of javax.swing. This would then force re-importing of any code to be ported as well. But Tao wants you to buy their UI is my guess so what can you do unless you can buy the UI from them? When I checked their web site they weren't offering individual licenses.
