Getting errors on copyright comment when trying to build PR

IDescribe the problem

I am getting errors on the copyright comment block when trying to build a PR.
The only differences I see are "Copyright 2020" vs "Copyright 2020-2021" and some additional spaces.
I made no change to the copyright block when I changed the code.

This is happening on many source files.

Provide the exact sequence of commands / steps that you executed before running into the problem

Create PR.

Start with the formatting failure for src/main/java/org/tensorflow/framework/initializers/He.java and inspect how the copyright comment differs from Spotless's expected output. Run the Maven spotless-check goal against the affected files, then confirm that the source files pass the PR build without copyright or spacing violations.
