Somebody is cleaning up SO and deleting posts (here and here). Instead is should have been moved here but I can't comment / edit / move it, so here is the question:

I know that sun/oracle stopped working on its jai_imageio libs a long time ago. Now if someone would still be using it - what license does it have? I checked it and it doesn't seem to be a standard one like apache/BSD or the like. Can anyone shed some light on it? Is it compatible with other standard licenses like Apache, BSD or LGPL? Is it deferred/similar to other known licenses?

Here you'll find the full text:

Is it compatible with other standard licenses like Apache, BSD or LGPL? Is it deferred/similar to other known licenses?

  • Superficially speaking, the restrictions seems to be in place to protect the JAI ImageIO classfiles from being modified, reverse engineered, or sub-licensed (as if you own any of it). Attributions to rwong – Lonzak Sep 9 at 19:27

I am not a lawyer, and all the usual disclaimers. ;-)

The link you have found, is the license for the JAI ImageIO product shipped by Sun/Oracle. Its license is that text you have found. It's not an open source license, and seems quite restrictive.

According to what I believe is the latest version of the source code at java.net, the license of the source code is BSD. Unfortunately, if you look at the project source control, you'll find that there are multiple licenses, covering different parts of the project, like native parts vs Java source code. I also believe that the JJ2000 (JPEG 2000 implementation) has its own license, that I have never been able to understand.

You will also find various forks around the web, fixing some issues. They mostly claim to be BSD-licensed.

Because JAI ImageIO is neither maintained, nor has an understandable license, I have created TwelveMonkeys ImageIO. This is an open source project, completely under BSD license, and actively maintained. It uses the same API as JAI ImageIO, and handles most formats supported by JAI ImageIO (and some more on its own).
