"Directory was previously created with a different LockFactory" when open, close, delete a repository in a loop

Description

Opening a TransientRepository in a loop throws the exception "Directory was previously created with a different LockFactory instance".

Test case:

for (int i = 0; i < 3; i++) {
FileUtils.deleteDirectory(new File("repository"));
Repository rep = new TransientRepository();
Session session = rep.login(new SimpleCredentials("", new char[0]));
session.logout();
}

The problem seems to be that org.apache.lucene.store.FSDirectory.DIRECTORIES is not cleared (FSDirectory.close() is not called?).

Stack trace:
