Is there a native implementation version of Java Advanced imaging api?

Is there a native implementation of the java advanced imaging api? We currently are using the j开发者_JAVA百科ar files

1-jai_core-1.1.3.jar

and

2-jai_codec-1.1.3.jar

I have heard there is an implementation of this api written with native code that runs much faster but cannot find it on the mess that is Oracle's website.

Any ideas?

There are native JAI extensions for Windows, Linux and Solaris available here: http://download.java.net/media/jai/builds/release/1_1_3/

They do run a lot faster. AFAIK there are no native extensions for OSX.
