-------------------------------------
Pretty cool idea!
> Full cutover to Path api from java.io.File

> Key: LUCENE-5945
> URL: https://issues.apache.org/jira/browse/LUCENE-5945
> Project: Lucene - Core
> Issue Type: Task
> Reporter: Robert Muir
>
> Using NIO2 has a lot of benefits:
> * more fine grained exception handling
> * clearer semantics about what happens
> * additional functionality
> * possibility to work with virtual filesystems, etc.
> We already banned File.delete and switched to Files.delete, I think we should
> ban File completely (except for some sugar methods that just forward with
> .toPath, like FSDirectory.open)
> For tests, ideally we go a little further and ban methods like
> FileSystems.getDefault(). Instead we could exempt LuceneTestCase and ensure
> all Paths are created via one protected method. This leaves open the
> possibility to mock up filesystem behavior at a lower level in tests in the
> future.
