Comment 4 Tomas Hoger 2016-12-05 13:41:10 UTC

The reproducer does not work against recent jasper versions.  However, that only seems to be a side effect of a different fix causing jasper to abort image parsing earlier, rather than actually being fixed.

Comment 6 Tomas Hoger 2017-03-01 14:23:09 UTC

Remains unfixed in 2.0.11.
