Bit of a status update

[Martijn Verburg]

Hi Kelly,

Thanks for the update.  I've managed now to get the combination of
build-infra and jtreg working, so we're looking to swap the Adopt
OpenJDK builds to use build-infra as std.

As per the existing build, I set PRODUCT_HOME in order for jtreg to
run, is that the correct way under build-infra, or was a new hook put
in?

Cheers,
Martijn
