When I landed https://chromium-review.googlesource.com/c/chromium/src/+/1088754 (I had forgotten that adding the headless tests triggers this)

Idea: https://chromium-review.googlesource.com/c/chromium/src/+/1089430

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/1c149502277c1441eec693c3ec160462e150000b

commit 1c149502277c1441eec693c3ec160462e150000b
Author: Nico Weber <thakis@chromium.org>
Date: Sat Jun 09 04:10:45 2018

Run headless tests on memory waterfall.

Relands the last missing bit of https://chromium-review.googlesource.com/1088754
This got reverted the last time because the msan bot had a too-old version of
Java.  This should now be fixed.

Resolved for now by fixing  issue 850731 . If devtools tests could not depend on java that'd be better though imo.
