Fix to static final
Comment From: sbrannen
Thanks for the PR.
For this particular use case, converting the field to static won't have any noticeable impact since the referenced field is itself a static singleton.
In addition, we typically do not use all caps for collaborators like the comparator here.
In light of the above, I am closing this PR.
