>          Components: jackrabbit-core, query
>            Reporter: Michael Neale

> 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).
