If you plan to write TIFFs with Tika (rendering of PDF pages for OCR) or read JPEG2000, and if the BSD-3 with nuclear disclaimer license is acceptable to you, include:

...

<dependency>
  <groupId>com.github.jai-imageio</groupId>
  <artifactId>jai-imageio-jpeg2000</artifactId>
  <version>1.4.0</version>
</dependency>

Note! In 2.x, Tika will not warn you if a PDF page that you're trying to render has a JPEG2000 in it.  PDFBox will log a warning.
