What Operating System are you using (both controller, and any agents involved in the problem)?

Jenkins controller running on Linux with one local agent launched via command execution on controller.

Reproduction steps

1. Create a freestyle project with a Base64 File Parameter named FILE and a shell step just running echo $FILE
2. Start the job with any file

Expected Results

The shell step should output base64 string.

Actual Results

FATAL: null

Anything else?

If I remove the shell step the job succeeds.

super.buildEnvironment(build, env);

should likely be removed. Possibly I never bothered to write tests for non-Pipeline projects.
