Unhandled exception in JHOVE JPEG2000-hul for balloon_oj.jp2

[RvanVeenendaal]

When running JHOVE against balloon_oj.jp2 from the format-corpus, JHOVE 1.34 and 1.30 end with an unhandled exception message. Jpylyzer 2.2.1 reports True without exception messages.

What is this property where a Null value is not permitted, and why does JHOVE halt while Jpylyzer seems to accept it?

This is the output of JHOVE 1.34 and 1.30:

Thanks for reporting this, I've added it to the v1.36 backlog and will take a look when the development for that starts.
