That's really strange. It's throwing a Headless exception from within the HeadlessGraphicsEnvironment! That means that the headless environment is being correctly set. (which was the original bug which was fixed in an earlier revision).

At first glance this looks like it has to be a bug in the core java class - especially as it seems to be SunOS specific.

As a test can you try setting a DISPLAY environment variable and see if it then works. It may be a redundant check for something which isn't actually required.
