The underlying issue with the PDF in question is that when the image on page 3 is loaded there is an error building the Huffman tree. I've been reviewing the code but have yet to find cause.
Basically when the 4 node is entered into the tree there appear to be a length issue where the the int 2316 is truncated into a 10 digit binarray number. So 100100001011 get truncated to 0100001011 as the Huffman path.
The problem here is that at node 421 we get the int 267 which when converted to binary is 0100001011 and we have a collision when building the tree.
The image is located on page 3 of the sample document BlackPagesCany.....pdf. I'll create a seperate but for this issue for for the time being we have code in place that will try and load the image using the levigo library and on failure will fall back and try to load the image using the default core implementation of the Jbig2 which address the test cases attached to this case.
