      Description

      The native J2K Image Reader (J2KImageReaderCodecLib) produces display artifacts
      when decoding 12-bit lossy-compressed images. Some images (not all) appeared on
      screen with grid effects.

      Images are displayed correctly with the pure-Java Image I/O J2KImageReader or
      with other JPEG2000 decoders.
