[jira] [Commented] (LUCENE-9325) Sort and SortField are not
immutable
[ https://issues.apache.org/jira/browse/LUCENE-9325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17422763#comment-17422763 ]
Alan Woodward commented on LUCENE-9325:
---------------------------------------
Picking this one up again: I've opened [https://github.com/apache/lucene/pull/338] to make `Sort` final. `SortField` is a bit more complicated so I'll do that separately.

> Key: LUCENE-9325
> URL: https://issues.apache.org/jira/browse/LUCENE-9325
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Alan Woodward
> Assignee: Alan Woodward
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h

> The `Sort` and `SortField` classes are currently mutable, which makes them dangerous to use in multiple threads. In particular, you can set an index sort on an IndexWriterConfig and then change its internal sort fields while the index is being written to.
> We should make all member fields on these classes final, and in addition we should make `Sort` final itself.
