The java-1.4.2-gcj-compat rpm more-or-less ``correctly'' provides
jaxp_parser_impl since the necessary classes are in rt.jar, so xerces-j2 isn't
needed. However, in practice whenever I tried to build or run packages 
with the
GNU jaxp or transform implementations, it would fail.

Installing xerces-j2 fixes the problem since it has a higher alternatives
priority, but since xerces-j2 is not explictly required we do end up with
inconsistent build environments where one cannot be sure which jar was 
actually
used to build a package (but I assume most, if not all, use xerces-j2).

In short, the java-1.4.2-gcj-compat does what it's supposed to, but I don't
think that the classes are actually compatible based on experience.
