New cimg causing github job issue

Hey, When running a job with our current image circleci/openjdk:11-jdk-stretch we only need this line.
git config --global “$CIRCLE_USERNAME”

but when I switch to cimg/openjdk:11.0.0 I get this error.

fatal: unable to auto-detect email address (got ‘circleci@ffbbab3d4fab.(none)’)

I can stop the error by manually adding my email to the job, but I would like to not have to do that.

What changed in the new images, and is there anything I can do to fix this?
