One other late-breaking issue may we "what to do about the fact that Java 7 & 8 have a broken sort algorithm?, which has surfaced recently<http://envisage-project.eu/proving-android-java-and-python-sorting-algorithm-is-broken-and-how-to-fix-it/>
I believe some other OSS projects have tried to address this. Looking at LUCENE–6293, they weren’t clear whether it was worth the effort for a problem that didn’t corrupt their data. I’m fairly tempted to argue the same for doing something for 2.7, especially as a switch throughout the code base could be expensive. Except: what if Oracle don’t ship a patch for JDK7? -Steve
