JComponent leaks an Autoscroller each time autoscrolling is turned off (after being on). JComponent sets its autoscroller reference to null and calls
Autoscroller.stop. Autoscroller.stop
is not really appropriate as it does not de-register the autoscroller from its views, which in turn makes sure the Autoscroller instance never gets GC'ed. Autoscroller probably needs a dispose method. It would be great if the implementor also took the trouble to fix 4138158, a critical autoscrolling bug, while in the vicinity.
Below is the a simple program that should run forever but instead crashes as the VM runs out of memory:

import javax.swing.JList;
public class Leaky
{
    public static void main(String[] argv)
    {
        JList list = new JList();
        while (true)
        {
            list.setAutoscrolls(!list.getAutoscrolls());
        }
    }
}
