FC6 ships gcj instead of the Sun Java SDK. Recent version of gcj do
mostly work with jmol, but FC6's gcj is known to be broken. I would
recommend to install the Sun Java SDK. Alternatively you could update
the gcj runtime, but that is potentially painful and will likely break
other Java related things.
