The argument to the Fact constructor is just the "head" of the fact,
not all the slot data; you have to add the slot data manually
afterwards (see sections 4.7.1 - 4.7.3 in the Jess 6.0a8 manual.)
So although you want a fact ("a" "bob" "stewart") you've instead
created a fact ("a bob stewart"). So you want something like
Fact fact2 = new Fact("a", r);
ValueVector vv = new ValueVector();
vv.add(new Value("bob", RU.ATOM));
vv.add(new Value("stewart", RU.ATOM));
fact2.setSlotValue("__data", new Value(vv, RU.LIST));
Of course, r.executeCommand("(assert (a bob stewart))") works too.

Note that reset clears all the facts on the fact-list, including the
one you've asserted just above! Call reset before asserting your
facts.
