OPJ fails to decode attached image:

[11:59:09 ~/dev/opj/git/openjpeg-build/bin] opj_decompress -i ~/Downloads/opj_wrong_kdu_ok.jp2 -o ~/Downloads/opj_wrong_kdu_ok.jp2_opj.ppm

[INFO] Start to read j2k main header (85). [INFO] Main header has been correctly decoded. [INFO] No decoded area parameters, set the decoded area to the whole image [INFO] Header of tile 0 / 1 has been read. Expected SOP marker Error : expected SOP marker Error : expected EPH marker read: segment too long (4) with max (0) for codeblock 0 (p=0, b=1, r=5, c=1) [ERROR] Failed to decode. [ERROR] Failed to decode tile 1/2 [ERROR] Failed to decode the codestream in the JP2 file ERROR -> opj_decompress: failed to decode image!

While kakadu decodes it correctly:

[12:00:15 ~/dev/opj/git/openjpeg-build/bin] kdu_expand -i ~/Downloads/opj_wrong_kdu_ok.jp2 -o ~/Downloads/opj_wrong_kdu_ok.jp2_kdu.tif

Consumed 2 tile-part(s) from a total of 2 tile(s). Consumed 110,407 codestream bytes (excluding any file format) = 1.179209 bits/pel. Processed using the multi-threaded environment, with 4 parallel threads of execution

First investigation shows that 16th tile-part is read beyond its end => this makes openjpeg start reading 17th tile-part at a wrong place, and explains why it does not find SOP nor EPH marker.
