JDK-4864304 - Improve memory consumption of Swing apps
Description
Autoscroller is currently rather heavy and could be improved by:
. Making it a singleton thereby reducing a JComponent field and indirectly
  sharing the Timer that was contained in it.
. Rather than have Autoscroller implement MouseListener JComponent should
  forward the mouse released event, thereby making it unnecessary for
  Autoscroller to implement MouseListener and be added as a MouseListener.
. Make Autoscroller implement ActionListener instead of using an anonymous
  inner class.
Comments
EVALUATION Description says it all. In order to no longer add Autoscroller as a MouseListener JComponent will need to override processMouseEvent and forward the event to the Autoscroller. ###@###.### 2003-01-27 This work was done under the umbrella performance bug 4864304, closing as a duplicate. ###@###.### 2003-08-12
