yeah, I'm trying to set some of the common ones up first

it's a bit confusing making sense and isolating JVM updates with other test
failures, especially as some of the failures seem intermittent, and some of
the test runs (hadoop-hfds-trunk) don't even collect all the test results
=E2=80=94you see a "build fail" message without any failure tracking.

expect more "jenkins failed" messages as I'm going to be triggering more
test runs than usual (UK time)
