jaxp: we have gnujaxp, don't we?
antlr is in debian main (free)
javamail: we have gnumail etc...

I think we have some packages that could replace those non-free or that
are free.

I'm thinking about argouml, or some other packages that are stuck in
contrib because of javax.swing.html.* etc. If those packages cannot be
build, we can't upload them to the pool so we can't integrate them in gump.

[Just a note for the gump users: we wanna use gump to test the runtimes
and compilers, not to tests the other java softs ;-)]

That was not was I was thinking about: if tests do not pass, the package
must be uploaded with a note that it can't be run with free-JVM.
