-----------------------------------
Hi Ryan,
this patch causes tons of unchecked warnings, without it, Lucene compiles
without any.
The generics policeman does not understand this code so he cannot fix:

> Add sort missing first/last ability to SortField and ValueComparator
> --------------------------------------------------------------------
>
> Key: LUCENE-2671
> URL: https://issues.apache.org/jira/browse/LUCENE-2671
> Project: Lucene - Java
> Issue Type: New Feature
> Components: Search
> Reporter: Ryan McKinley
> Assignee: Ryan McKinley
> Fix For: 4.0
>
> Attachments: LUCENE-2671-SortMissingLast.patch
>
>
> When SortField and ValueComparator use EntryCreators (from LUCENE-2649) they
> use a special sort value when the field is missing.
> This enables lucene to implement 'sort missing last' or 'sort missing first'
> for numeric values from the FieldCache.
