java - Erratic auto-scrolling in JList -


i'm trying create jlist allows re-order items in list dragging them. working ok, except auto-scrolling behavior jerky , erratic. when grab item in list , drag bottom of list, expect scroll smoothly , continuously, scrolls few pixels , stops. if jiggle mouse cursor around edge of jlist, continues scrolling few pixels @ time, not acceptable behavior.

does have suggestions on how fix this?

in case matters, i'm running java 6 on mac os x 10.8.3.

import javax.swing.*; import java.awt.*; import java.awt.datatransfer.stringselection; import java.awt.datatransfer.transferable;  public class draggablejlist {     public static void main(string[] args) {         eventqueue.invokelater( new runnable() {             public void run() {                 int count=200;                 string[] elements = new string[count];                 for(int n=0; n<count; n++ ) {                     elements[n] = string.valueof( n );                 }                  jlist list = new jlist( elements );                 list.setdragenabled( true ); //if disable line, smooth scrolling, can't drag items re-order them                 list.setdropmode( dropmode.insert );                 final transferhandler transferhandler = new transferhandler() {                     @override                     public int getsourceactions( jcomponent c ) {                         return transferhandler.move;                     }                      @override                     protected transferable createtransferable( jcomponent c ) {                         return new stringselection( "hey there" );                     }                 };                 list.settransferhandler( transferhandler );                  jscrollpane scrollpane = new jscrollpane( list );                 jframe frame = new jframe();                  jpanel borderpanel = new jpanel();                 borderpanel.add( scrollpane );                 borderpanel.setborder( borderfactory.createemptyborder( 40, 40, 40, 40 ) );                 frame.setcontentpane( borderpanel );                 frame.pack();                 frame.setvisible( true );             }         } );     } }
