Description

See https://github.com/google/error-prone/issues/2668. The next release of error-prone will contain https://github.com/google/error-prone/pull/2669 and https://github.com/google/error-prone/pull/2676, which will help us.

Until then we've had to suppress the check in several places. This jira tracks upgrading to a new error-prone once released and removing the suppressions.
