I raised 31 (~10% of the total) representative bugs, trying to get good
coverage on the type of issues:


These four are probably the most important:

#873247 [src:xmlstreambuffer] FTBFS with Java 9: javax.activation has gone
#873249 [src:uimaj] FTBFS with Java 9: javadoc classpath with maven?
#873250 [src:xml-commons-external] FTBFS with Java 9: overrides core packages
#873252 [javatools] Can't opendir($fh, '.../debian/...-doc/usr/share/doc/libpirl-java/

The Swing ones this email was originally about are labelled as "Terrible Swing".

I've been using a ~20 line Makefile and a couple of Dockerfiles. Not
very Debian-y, but I never got along with sbuild/pbuilder or any of
those things. Big advantages here are:

 * no leaked processes, ever
 * really quick to jump back into a failed build to see what's going on
 * cheap setup; very easy to get an base image with a patched jdk installed

Big advantage of renting a huge machine and running everything on there
is that you can get away with doing a lot of things by hand.

The code has always been here: https://github.com/FauxFaux/debjdk9
I've added some more descriptive usage instructions, in the hope that it
might be useful for people who aren't me.
