Typically, input file patterns are validated during Pipeline
construction, but standard Read transforms include an option to disable
validation. This is generally useful but can lead to cases where a
Pipeline executes successfully with empty inputs.
This changes the behavior to fail execution on empty file-based inputs
even when validation is disabled.
