Rebuilding Debian with Java 9

It's about three months until Java 9 is supposed to be released. Debian contains around 1,200 packages that build against Java 8. I have been trying to build them with Java 9.

It's not been going well.

The first attempt found an 87% failure rate, the majority of which were either:

This is too bad to get an idea of what's actually broken, so I gave up.

The second attempt has gone better, only 57% failures. This had a number of issues fixed, but there's still a large number of problems masked by toolchain failures.

However, some real Java 9 breakages are coming to the fore!

Oh, and 135 packages have an unknown problem, so maybe there's a whole other class of bug I've missed.

This is (obviously) an ongoing project, but I thought I'd write up what I'd seen so far.

Also, I wanted to mention how cool it was to hack up a dashboard for your ghetto make/Docker build process in ghetto shell, although slightly less ghetto than the previous shell.
