Tilman Hausherr commented on PDFBOX-2034:
-----------------------------------------
Done in rev 1591050 for the trunk and rev 1591051 for the 1.8 branch. It now
does 10 loops based on a fixed seed and 10 loops based on a truly (according to
the javadoc) random seed. Will set to resolved after the release of 1.8.5. (of
which this fix won't be part of)
> TestFilters is non-deterministic

> Key: PDFBOX-2034
> URL: https://issues.apache.org/jira/browse/PDFBOX-2034
> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 1.8.5, 2.0.0
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Minor
> Labels: LZW
>
> This is a follow-up of PDFBOX-1977, which was created by John.
> ====
> TestFilters uses Random().nextLong() to generate a seed for random data,
> which means that it is non-determinate. Depending on the seed value, the test
> may fail or succeed.
> ====
> So what we need is:
> - a set of [deterministic
> tests|http://martinfowler.com/articles/nonDeterminism.html]
> - a set of non-deterministic tests
> To see why, see the discussion in PDFBOX-1977.
