Fixed version: N/A
Upstream bug is still open and unfixed. The issue is not reproducible in version 1.900.26 and later, as there's limit on maximum number of samples in one image used in those versions. The issue is reproducible in the latest 2.0.12 when no samples limit is used (specified using --max-samples 0 option for jasper command line tools).
