Comment (by Pierre-Anthony Lemieux):

 > How did you get j2k-samples/j2k1.j2c? What created it?

 It is a test file I've had for a while. According to the headers it looks
 like it was created by Kakadu 8.0.3. Using the latest demo executables, I
 get j2k1.8_0_5.j2c, which decodes to the same pixels as j2k1.j2c, but is
 smaller.

 Looking at the differences, it looks like, for whatever reason, j2k1.j2c
 contains bad bytes beyond the first FFD9 (end of codestream marker).

 So I suggest changing the title of the issue to "J2C decoder should ignore
 any data that appears after End of Codestream marker 0xFFD9".
