I don't know about that bug, but in general, yes, this is almost a
solution ton one problem I can imagine. You could do the comparisons
using strcasecmp instead of strcmp, and a case-ignoring hash function,
and then be case insensitive, so that you would find "fOo.JaVa" as
well as "foo.java" when looking for a class "foo".
