I've been working on using 12.0.45 as a server-side static graphics engine for
the SageMath group. I've run into the following problem. The server does not
run in an X-session, so there is no graphics environment. This causes an error
when Jmol is run as Jmol.jar -ionx. The error seems to imply that we are still
initializing the look-and-feel, even when there is no GUI. Is there any reason
we can't switch this off? Here's the error:
