Pushing ahead as it looks like we are going to have to fix this with our own edits to a Java JPEG2000 library or do a fresh port of C or JavaScript implementation.

We've seen this issue in the past. The image in question is in the JPEG2000 format and it appears that there might be a decode issue. Around each of the black circles is four white squares which is probably related to the artifacts. Further work is needed to debug this as the JPEG2000 image format is non trivial.
