              This is a strange bug but should be relatively easy to fix. The jbig images decodeParams points to an empty stream object (13 0 obj) that has a specific length of zero. Our stream parser seem to ignore this and return a few bytes between the stream .. endstream which is throwing off the jbig decoder.

              We can take a look at fixing the stream parser to check the stream length or we can add a few checks in the jbig decode to makes sure the decode params length is valid.

              Same customer has reported another very similar issue in that the exceptions are the same. Attaching PDF.

              Likely also related to PDF-342 moving out to 5.0.

              We've secured a license for a new JIG2 library that can correctly decode the examples in question. We'll e adding the new library in 5.1 PRO.

              We are moving away from the jbig2 implementation provided by jpedal and are moving to the Levigo library. The library is licensed under LGPA so we won't be distributing it with the OS bundle but if added to the class path ICEpdf will try to use it.

              We licensed a special commercial version of Levigo which we are shipping with the PRO version for our enterprise customers.
