>                 Key: FOP-3040
>                 URL: https://issues.apache.org/jira/browse/FOP-3040
>             Project: FOP
>          Issue Type: Bug
>            Reporter: Bernhard M. Wiedemann
>            Priority: Major
>
> When you use the same input to create PDF output twice, results will vary from IDs, Time and something else.
> [https://github.com/apache/xmlgraphics-fop/pull/65] fixes the time portion, but more fixes are needed for fully deterministic bit-identical output.
> Especially the diff
> {{-/BaseFont /EAAAAC+DejaVuSansMono}}
> {{+/BaseFont /EAAAAC+DejaVuSansMono-Bold}}
> looks like a bug worth debugging outside of the context of reproducible builds.
> See [https://reproducible-builds.org/] for why this matters.
