[jira] [Resolved] (LUCENE-5953) Make LockFactory final on Directory

     [ https://issues.apache.org/jira/browse/LUCENE-5953?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Uwe Schindler resolved LUCENE-5953.
-----------------------------------
    Resolution: Fixed

I committed this. We may think about making 

I also noticed that (at least on my windows machine), Snapshooter sometimes fails with a crazy NoSuchFileException when trying to *write* a snapshot. To me it looks like a multi-threading issue, which may not be related to the changes here. We will see on jenkins.

Nevertheless, Snapshooter should be removed (as far as I understand from the comments in the code because it is no longer used).

> We should remove the setters for the LockFactory from Directory and make the field final. It is a bug to change the LockFactory after creating a directory, because you may break locking (if locks are currently held).
> The LockFactory should be passed on ctor only.
> The other suggestion: Should LockFactory have a directory at all? We moved away from having the lock separately from the index directory. This is no longer a supported configuration (since approx Lucene 2.9 or 3.0). I would like to remove the directory from LockFactory and make it part of the Directory only.
