This was a patch submitted by a user awhile back. The reason is that if 
an application uses any of the image libraries in AWT (it's pretty 
common these days to use capthas for exmaple), the JVM will fail if 
graphics libraries are not installed. Since we don't really have a need 
to launch GUI elements at this point it makes sense to save these users 
some heartache. As to a database admin thing, we ship H2 for sample 
usage, and they don't use swing. They provide an admin war though, that 
we show how to deploy in one of the quickstarts.
