Description Jesse Glick 2007-07-27 19:40:23 UTC 
See URL for an example, excerpted here:

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
	at java.util.ArrayList.RangeCheck(ArrayList.java:546)
	at java.util.ArrayList.get(ArrayList.java:321)
	at org.openide.explorer.view.VisualizerNode.getChildAt(VisualizerNode.java:261)
	at javax.swing.tree.DefaultTreeModel.getChild(DefaultTreeModel.java:156)
	at org.netbeans.jemmy.operators.JTreeOperator$3.map(JTreeOperator.java:462)
	at org.netbeans.jemmy.operators.Operator$MapAction.launch(Operator.java:1234)
	at org.netbeans.jemmy.QueueTool$QueueAction.run(QueueTool.java:541)

I have seen this same stack trace a number of times in the past.
Comment 1 Jesse Glick 2007-07-27 19:41:18 UTC 
Often breaks CND commit validation.
Comment 2 Jiri Skrivanek 2007-08-01 16:22:34 UTC 
Fixed in JTreeOperator#chooseSubnode. We need to catch IndexOutOfBoundsException from getChild and return null (it means
tree has been re-generated and we need another iteration to find a proper tree path).
