This is the best project I could find until this day that supports JPEG2000/J2K images:

It also provides good documentation to use:

With the Java library imageio-openjpeg (Apache 2 license) you can use Jpeg2000 files (*.jp2) with the imageio API from Java. It is based on OpenJPEG (BSD license). Since 2015 is OpenJPEG the reference software of the Jpeg2000 standard.

If you want use it then you need both imageio-openjpeg and the OpenJPEG for your platform.

The only options I know are all based on jj2000.

jai-imageio-core provides support through an additional third-party module:

https://github.com/stain/jai-imageio-core

https://github.com/jai-imageio/jai-imageio-jpeg2000

It'll register itself with ImageIO and you'll then be able to read jpeg2000 files as you would any png, bmp or jpeg.

Although jj2000 is in itself an option, the api is not designed for day-to-day use.

Other options include JMRTD, which provides its own wrapping for jj2000, or a commercial offering, JDeli.

Apparently the support of jpeg2000 / ( .jp2 ) files has been removed from Java Advanced Imaging (JAI).

By un-installing JAI 1.1.3 and installing the older version 1.1, I'm now about to read .jp2 files and no longer see the null pointer.

Version 1.1 is available here. http://download.java.net/media/jai-imageio/builds/release/1.1/

Version 1.1 lists codec's for - g3fax g4fac jiio jp2k jpeg and png

You would do it in this way

Image img = ImageIO.read(new ByteArrayInputStream(imageBytes));
ImageIcon imgIcon = new ImageIcon(img);

JLabel label = new JLabel(imgIcon);

but the JPG2000 decoder isn't supplied with standard SDK, you should head here (Java Advanced Imaging) and use the right decoder for that format..
