upgrade to checkstyle 8.35 & release this as 2.7
There is already checkstyle 8.37 out there, but the eclipse plugin only supports 8.35 at the moment (IntelliJ similarly only has 8.36.2 right now).
I backported a few easy "wins" from checkstyle 8.36 and 8.36.1 (see 7cf5ff2e and 867743ac) to get improve the compatibility to the actual google java code style even more.
