This is a demonstration patch and is not meant to be merged.

Ant build completes under jdk 9.0.1
but with AutoValue annotation processor failures
the resulting buck binaries are unable to build buck

for autovalue annotation processor failures -- see google/auto#560 and related tickets

Question for the buck maintainers -- clearly this patch is not backward compatible with java 8. what's the policy for this project?

@epkugelmass have you tried to build Java 9 code with buck using out of the process compilation?

[bobyangyf]

Unfortunately buck doesn't work with Java 9.
There's a number of issues in terms of compatibility that even if we were to get it to build, buck would not run properly.

It is on the backlog to modernize it newer standards of java.
