Well, I'm going to ignore that for now as it's a java 8 problem, surfacing this weekend once the builds were actually switched to Java 8. memory size tuning can continue. I have now committed the Java 7+ only patch to branch-2 and up: new code does not have to worry about java 6 compatibility unless they plan to backport to Java 2.6 or earlier. Having written some Java 7 code, the <> constructor for typed classes are a convenience, the multiple-catch entries more useful, as they eliminate duplicate code in exception handling. Getting this patch in has revealed that the Jenkins builds of hadoop are (a) a bit of a mess and (b) prone to race conditions related to the m2 repository if >1 project builds simultaneously. The way the nightly builds are staggered means this doesn't usually surface, but it may show up during precommit/postcommit builds. The switch to Java 7 as the underlying JDK appears to be triggering failures, these are things that the projects themselves are going to have to look at. This then, is where we are with builds right now. This is not a consequence of the changes to the POM; this list predates that patch.
