After every call of the method getFileSystemView of FileSystemView a new listener are created and added to UIManager. But logically there is need only one!

These listeners are never removed and a pile of such listeners slows UIManager notifications.

Below is the bad code:

        UIManager.addPropertyChangeListener(new PropertyChangeListener() {
            public void propertyChange(PropertyChangeEvent e) {
               if (e.getPropertyName().equals("lookAndFeel")) {
                   useSystemExtensionsHiding = UIManager.getDefaults().getBoolean("FileChooser.useSystemExtensionHiding");
               }
            }
        });

N/A

To remove from the "FileSystemView#getFileSystemView" method creation of a new listener and adding it to UIManager
