Hi Kasun, No, there will be numerous bug fixes (and features, and also some API changes) and all with latest Lucene library. So we have to keep current with that. I don't see a problem of ML product also making JDK7 a requirement, and any product that will maybe embed those components. We just will be building our repo with JDK7, others can build with JDK6, and package it up in a product, and run it in JDK7.
Cheers, Anjana.
