Debian and Ubuntu use the same sources to provide both ecj and ecj1.
ftp://sourceware.org/pub/java/ still has 3.5 as the latest version available.
If Fedora ships an updated ecj1, then it would be nice to see this "upstream" as
well.

Hi,

Fedora uses eclipse as upstream for ecj, not the source bundles at
that ftp site.

But, you've reminded me of something.  The ecj package does add an
alternative entry point (used by gcc/gcj).  This comes from the
sourceware.org:/cvs/rhug repository.  I had to patch the newest[1]
sources there a tiny bit due to ecj change:

I really meant to follow up to upstream this, what is the right
way to do that?  (I am totally fine with someone committing this
on my behalf, by the way, but in general I would like to know
better if there is some mailing list where changes should go).

thanks,
jon

I'll second that.  I'm surprised 3.8.2 works with the current gcj actually,
as when I tried it, it complained about missing javax.lang.model code which
is now in GNU Classpath but not yet in gcj.

Do you know the process for updating the copy used by gcj?
