Jingle Plugin Licensing?

The Jingle plugin for Spark is in trunk/src/commercial I was under the impression that the jingle portions of smack/spark would be open sourced licensed.

The README.txt file in trunk/src/commercial indicates that commercial code licensed by Jive was used to create the plugins in that directory.

Does that means only certain jar files within jingle.jar are not under open source licenses? If so, which ones?


where can I download the Jingle Plugin(Jingle.jar) and its javadoc?thank you!
