Sorry to spam you :) We tested with a jp2 file from autotest directory: 3_13bit_and_1bit.jp2, OpenJpeg lib 2.0 and GDAL 1.11. We had the same problem. Building gdal with debug mode we had the following debug info: GDAL: AutoSkipDriver(JP2ECW) OPENJPEG: info: Start to read j2k main header (1427). OPENJPEG: info: Main header has been correctly decoded.

() So gdal or the openjpeg lib mix information (check width and height for each bands). We updated openjpeg lib to 2.1 and gdalinfo worked as expected. We will test gdal 1.10 with OpenJpeg 2.0 to check that the problem is already there as we would like to use GDAL 1.10 but I am afraid we should use gdal 1.11 and OpenJpeg 2.1.
