flake8 parser complains about empty file if no violations

I am running flake8 as part of my pipeline. There are no violations, so the log file is empty.

When calling `recordIssues` on the file, Jenkins reports two errors about the file being empty (which is the default if no violations occur):

Errors during parsing
Skipping file 'flake8.log' because it's empty
Errors during parsing
Skipping file 'flake8.log' because it's empty

 
I could not identify a usable (non-hacky) way to disable this warning, probably originating from https://github.com/jenkinsci/warnings-ng-plugin/blob/250c0d7ce19c273ff011690b783baa543e93b146/plugin/src/main/java/io/jenkins/plugins/analysis/core/model/FilesScanner.java#L89
 
Relevant call in pipeline after generating the actual linting report:
 

recordIssues(tools: [flake8(pattern: 'flake8.log')])

 
These errors should not occur or a clean solution should be available/documented.
