I'll will try my best to assist you, but as you know this is a little
difficult for me. To make the situation a little worse Mark is
currently on vacation.

Anyway on the bright side, the failing tests are related to a single
issue in openjeg. To reproduce create a fake -tiff- image with small
dimension:

$ tiffinfo /tmp/t.tif
TIFF Directory at offset 0x3008 (12296)
  Subfile Type: (0 = 0x0)
  Image Width: 64 Image Length: 48
  Resolution: 72, 72 pixels/inch
  Bits/Sample: 8
  Compression Scheme: None
  Photometric Interpretation: RGB color
  Extra Samples: 1<assoc-alpha>
  Orientation: row 0 top, col 0 lhs
  Samples/Pixel: 4
  Rows/Strip: 64
  Planar Configuration: single image plane
  DocumentName: /tmp/t.tif



$ itkReviewTests5 itkJPEG2000ImageIOTest03 t.tif out.j2k
...

ExceptionObject caught !

itk::ExceptionObject (0xfe6e20)
Location: "virtual void itk::JPEG2000ImageIO::Write(const void*)"
File: /home/mathieu/tmp/git/ITK/Code/Review/itkJPEG2000ImageIO.cxx
Line: 854
Description: itk::ERROR: JPEG2000ImageIO(0xfd9c70): failed to encode image



Program exited with code 01.
...

It fails deep down in j2k_encoding_validation.

We may need an openjpeg guru...

thx
