              The PDF generator in question is doing a strange circular reference when specifying an JBIG2 images JBIG2Globals. Basically the reference points back to the original image which is incorrect. Normally if no JBIG2Globals are specified the value should be null or omitted.

              Good news is that it's an easy fix to get the Image in question to render correctly.

              Added instance of check to make sure we get the correct jbigGlobals instance.
