The DUCC parent pom has a section for the maven-jar-plugin manifest configuration which adds <index>true</index>. My reading of this is that it is designed for collections of Jars - where the index is built in such a way as to have all the entries for all the Jars, to enable applets to avoid downloading Jars just to search their contents. (The 1st Jar has the index for all the Jars).
I don't think this usage in individual Jars helps anything, and just takes up space... Other opinions? -Marshall
