A simpler way to reproduce:
public void testIt() throws Exception {
Repository repo = new TransientRepository();
Session sess = repo.login(new SimpleCredentials(foo,
password.toCharArray()));
Node root = sess.getRootNode();
for (int i = 0; i 10; i++) {
root.addNode( + i + System.currentTimeMillis(),
nt:unstructured );
sess.save();
}
Query q = sess.getWorkspace().getQueryManager().createQuery( select *
from nt:unstructured, Query.SQL);
QueryResult qr = q.execute();
NodeIterator ni = qr.getNodes();
assertTrue(ni.hasNext());
assertNotNull(ni.next());
assertNotNull(ni.next());
assertNotNull(ni.next());
//sess.logout();
}
I am just trying out to see if not closing the session can cause this. Take a
lot of iterations to reproduce it.

Michael Neale commented on JCR-778:

OK looking a little deeper, the problem stems from:
public Lock makeLock(final String name) {
final File lockFile = new File(directory, name);
return new Lock() {
public boolean obtain() throws IOException {
if (DISABLE_LOCKS) {
return true;
}
return lockFile.createNewFile();
}
In FSDirectory in jackrabbit core. IT seems that it is using an empty file as a
lock, yet when you look at JRE source for createNewFile, it EXPLICITLY says not
to use this for file locking:
* Note: this method should inot/i be used for file-locking, as
* the resulting protocol cannot be made to work reliably. The
* [EMAIL PROTECTED] java.nio.channels.FileLock FileLock}
* facility should be used instead.
So this is a problem I believe.
