Steve,

I've investigated and those JPEG2000 files have a particular characteristic 
that triggered a regression dating back to openjpeg 2.2.0

I've just fixed it in openjpeg master per
https://github.com/uclouvain/openjpeg/pull/1121

So I'd suggest you to track openjpeg master (or revert back to 2.1.2, but 
you'll loose performance optimizations)

Note: the sample file you provided to me has also a non-conformity (declaring 
codestream "Profile 0" but with tile dimensions of 1024x1024 instead of 
128x128 as expected) in the codestream header, as pointed by Kakadu, but that  
is not critical
