Thats certainly an option, but I didn't want to make the initial proposal
to broad. :-) toString() is a method of java.lang.Object,
so JavaObject#STRING could indeed just call toString without checking
for the class of obj. In fact, the more I think of it the better it
sounds.
If there is consensus, I can prepare an update patch if need be (its
simple enough anyways).
