Ok, Martijn's linked failing run was a jdk8 hs run with compressed refs turned on.

In the most recent runs, jdk_lang has been skipped when it was run with compressed refs enabled, but passes 100% of the time on the most recent runs with compressed refs turned off,

Note: There's no sign of an exclusion for this unit test, and my 100-strong grinder shows that this test passes just fine on this machine, using the jdk8 jvm, with compressed refs turned off.

Will have a poke around to see why we're now consistently skipping compressed refs disabled runs.

Edit: Some time between now and the 20th of January, something changed so compressed ref tests are skipped on non-cr platforms (by non-cr, I mean linux_x86-64 as opposed to linux_x86-64_cmprssptrs). I re-enabled them in a branch of TKG and ran the test on test-docker-ubuntu2010-x64-2. It passed.

Here's 100 of the same. If all of these pass, I vote we close this issue as "could not reproduce".

100 runs, 100 tests passed. Could not reproduce. Closing.
