heh - my jetlag is full effect - I wasn't looking at the lockdir, I was looking at:
{code} String lockClassName = System.getProperty("org.apache.lucene.store.FSDirectoryLockFactoryClass");
{code}
*edit
I'm too tired to be emailing - how about deprecating this one though?

> A user requested we add a note in IndexWriter alerting the availability of NativeFSLockFactory
(allowing you to avoid retaining locks on abnormal jvm exit). Seems reasonable to me - we
want users to be able to easily stumble upon this class. The below code looks like a good
spot to add a note - could also improve whats there a bit - opening an IndexWriter does not
necessarily create a lock file - that would depend on the LockFactory used.
> {code} <p>Opening an <code>IndexWriter</code> creates a lock file
for the directory in use. Trying to open
> another <code>IndexWriter</code> on the same directory will lead to a
> {@link LockObtainFailedException}. The {@link LockObtainFailedException}
> is also thrown if an IndexReader on the same directory is used to delete documents
> from the index.</p>{code}
> Anyone remember why NativeFSLockFactory is not the default over SimpleFSLockFactory?
