I am not a Reviewer in jdk8u but to gain experience of doing so I've reviewed this change.

The PR is not labelled "clean" but I'm not sure why, the patch is identical to that in 11u and applies with no fuzz.

As @sxa notes the pre-submit failure is an issue in the main 8u tree at the moment and is not specific to this change.

Test-only change. I've run it and it passes for me after this patch, although I haven't done a battery of runs to aggregate the results, like the backporter has.
