             Summary: Decompression Exception of Tiff Group 3 with T4 Options = 4
                 Key: IMAGING-143
                 URL: https://issues.apache.org/jira/browse/IMAGING-143
             Project: Commons Imaging
          Issue Type: Bug
          Components: Format: TIFF
    Affects Versions: 1.0
            Reporter: Josh Highley


I have multiple tiff images that are causing an "ImageReadException: Decompression error".
 All are Group 3 (T.4) encoded with T4Options tag value 4 (zero fill to byte).  Other Group
3 images without T4Options 4 work fine.

Stepping through Imaging 1.0 RC7, the hasFill boolean is being set properly to true. The exception
is thrown at the bottom of method HuffmanTree.java decode(bitStream).  Nothing is passed to
this method indicating zero fill or not.  I will attach a test image that reproduces the issue.
 The stack trace:
