My interests actually went into the other direction. Adding a
packageconfig which re-enables xawt.


While looking at it I tried to remove the DEPENDS on X11/GTK+ and came
to the conclusion that you would need to heavily change the source
tree / Makefiles to leave all the sources which include X11 (or GTK+)
headers out of the way.


The sources react to the symbol BUILD_HEADLESS_ONLY which promised to
keep the X11 dependencies out. However that is either broken in the
current versions of OpenJDK or never worked at all.
Some mailinglist post underlined that. e.g.
http://mail.openjdk.java.net/pipermail/build-dev/2012-March/005700.html


Maybe one could split openjdk-7-common and openjdk7-jre into packages
without X11 dependencies and the rest as Mario proposes. However I don't
know if that would lead to a working headless java installation.
