Ought I consider adding:


    forrest.addPrefixedParameter('-D','java.awt.headless','true','=')


.. to all Ant/Script invokes, not just forrest?

Ought I do this in code, or in the workspace, or expect the user to handle
it [somehow]?

Happens on gump.covalent.net as well (I run Xvfb on my machine for
just that reason).

If that actually helps.  I've never tried it and have no idea how
portable it is, but it probably won't hurt either.

Try it in your workspace with

<property name="java.awt.headless" value="true"/>

the same way as build.sysclasspath is handled.  We'll see whether it
really fixes something.
