Hi Anjana, Last JDK 6 compatible Lucene version seems to be 4.7.2 which was released on April last year. I know it's better to move with latest possible version, but as a platform we are constrained to support JDK 1.6 right now.
Did you guys see whether the JDK 6 compatible version will provide the needed functionality for you? It seems Lucene is a core requirement for BAM though I'm not sure about in-depth requirements. This not only affect BAM, but product ML is also affected. Any other product that will use the carbon-analytics repo are affected too since it's set to build only with JDK 7!! So, unless there's a very good reason, I think we should stick to JDK 1.6 support. WDYT??
