[jira] [Commented] (LUCENE-5514) Backport Java 7 changes from trunk to Lucene 4.8

["Uwe Schindler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-5514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13925354#comment-13925354 ] 

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.

> This issue tracks the backporting of various issues that are related to Java 7 to 4.8.
> It will also revert "build fixes" that worked around compile failures (especially stuff like {{Long/Integer.compare()}}.
> I will attach a patch soon (for review).
