>          Components: core/index

> MergePolicy.getMaxCFSSegmentSizeMB is final, but the corresponding setter is not, which means that overriding it with anything other than a trivial delegation can only lead to confusion.
> The patch makes the method final and removes the trivial implementations from MergePolicyWrapper and NoMergePolicy.
> [~mikemccand] also pointed out that the class name is nonstandard for similar adapter classes in Lucene, which are usually Filter*.java. Personally I was looking for MergePolicyAdapter, but if there is a prevailing convention here around Filter, does it make sense to change this class's name to FilterMergePolicy?
