Upstream bug report:

https://github.com/mdadams/jasper/issues/50

This issue is still not fixed in the current upstream git, i.e. not fixed in the latest tagged version 2.0.4.

Comment 5 Tomas Hoger 2017-03-01 14:23:35 UTC

Remains unfixed in 2.0.11.

Comment 6 Tomas Hoger 2017-12-11 10:38:01 UTC

Fixed now upstream via:

https://github.com/mdadams/jasper/commit/a10536d5f7f3164b0a1f1ae3e533f4a12ca6f543

Should be included in the next release, which presumably is going to be 2.0.15.
