ok ok ok, now we know when this problem occurs: it only occurs when
nillable="true" is set, which of course can't work with a primitive
(how should jibx set a primitive to null?)! so this behaviour is
correct, but the error message is so confusing that it took quite a
while to get me there ;-)
maybe this should go into the docs that using nillable=true implies
that no primitives can be used in setter and getter.
