> When autoSave is enabled on a FileConfiguration it's quite frequent to run into a ConcurrentModificationException,
simply because setProperty is called from a thread while another thread is saving the configuration.
> I suggest to leverage the ReadWriteLock in Java 5 to solve this issue. The read lock
is acquired in getProperty(), and the write lock is acquired in setProperty().
