-------------------------------------
Thanks for clarifying this, Uwe. Makes sense.
> FSDirectory ctor should use getAbsolutePath instead of getRealPath for
> directory

> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/store
> Affects Versions: 5.2.1
> Environment: OS X, Linux

> After upgrade from 4.1 to 5.2.1 I found that one of our test failed. Appeared
> the guilty was FSDirectory that converts given Path to Path.getRealPath. As
> result the test will fail:
> Path p = Paths.get("/var/lucene_store");
> FSDirectory d = new FSDirectory(p);
> assertEquals(p.toString(), d.getDirectory().toString());
> It because /var/lucene_store is a symlink and
> Path directory =path.getRealPath();
> resolves it to /private/var/lucene_store
> I think this is bad design decision because "direcrory" isn't just internal
> state but is exposed in a public interface and "getDirectory()" is widely
> used to initialize other components.
> It should use paths.getAbsolutePath() instead.
> build and "ant test" were successful after fix.
