Uwe Schindler commented on LUCENE-5514:
---------------------------------------
I think this is fine as a first step. It does not contain all the changes
needed to have identical Java 7 code in trunk and 4.x. The problem are merged
stuff that was fixed to be Java 6 compliant while merging. This is hard to
detect. Some of those were already fixed (like compare methods implemented with
Long.signum), but others like multi-catch not. I don't think we should put too
much effort in fixing this. It is important that the optimized methods for Java
7 are used in the comparators (intrinsics) and also the new FileChannel APIs
are used.
