Michael Neale commented on JCR-863:
-----------------------------------
I agree with Marcel. This is getting really nasty if we want to support from 1.4 through 1.6
(Java) in a non ugly fashion. Its also very hard to test.
Perhaps the better solution is to make upgrading to Lucene 2.1 a priority, so this code (which
is lucene specific anyway) can be retired and this JIRA closed.
> Patch to use FileLock for locking instead of empty file

> Key: JCR-863

> Issue Type: Improvement
> Components: query
> Reporter: Michael Neale
> Fix For: 1.4

> Attachments: FSDirectory.patch, JCR-863.patch

>
> The FSDirectory uses File.createNewFile to effectively lock a directory (in makeLock),
yet the Java Spec says explcitly not to use it for this purpose, and instead use FileLock
from nio.
> The attached patch shows how this is/could be done (change is internal to the makeLock
method only, and functionally equivalent, the same tests apply).
