I have a few headless servers, one is ancient and I tried on it, it has Java 1.6.0_07, java-runtime-headless, no x libraries, no x fonts, no GUI system or code at all, I checked everything that I could think of in the package manager, and the server still downloads its files and launches fine as of the latest version. Need more information. Start a trace on it and see what it locks on or something. Unless you have an idea for a package I may have missed?
