Hi Max, Yes the existence of this system property already in the script is a pain for integration with our metering engine as well as other code profiling solutions.

I don't know about other platforms, but on a Mac the presence of this flag prevents the creation of a dock icon and application menu bar.

Normally we don't want to see this when running a server.

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 quick starts.
