Hi, I'm using nb55 daily build 200606260200 with mustang b89. The issue arises when I tries to close one of many opened usage windows. The red alarm sign on right bottom corner sparkles and It's clicked to pop up the exception windows with exception like following: java.lang.ArrayIndexOutOfBoundsException: 1 >= 1 at java.util.Vector.elementAt(Vector.java:431) at javax.swing.JTabbedPane.getTitleAt(JTabbedPane.java:1089) at javax.swing.plaf.basic.BasicTabbedPaneUI.paintTab(BasicTabbedPaneUI.java:837) at javax.swing.plaf.basic.BasicTabbedPaneUI.paintTabArea(BasicTabbedPaneUI.java:818) at javax.swing.plaf.basic.BasicTabbedPaneUI.paint(BasicTabbedPaneUI.java:772) at javax.swing.plaf.ComponentUI.update(ComponentUI.java:143) at javax.swing.JComponent.paintComponent(JComponent.java:738) at javax.swing.JComponent.paint(JComponent.java:1002) at org.netbeans.modules.refactoring.ui.CloseButtonTabbedPane.paint(CloseButtonTabbedPane.java:168) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JLayeredPane.paint(JLayeredPane.java:559) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paint(JComponent.java:1011) at javax.swing.JLayeredPane.paint(JLayeredPane.java:559) at javax.swing.JComponent.paintChildren(JComponent.java:839) at javax.swing.JComponent.paintToOffscreen(JComponent.java:5091) at javax.swing.RepaintManager$PaintManager.paintDoubleBuffered(RepaintManager.java:1360) at javax.swing.RepaintManager$PaintManager.paint(RepaintManager.java:1291) at javax.swing.BufferStrategyPaintManager.paint(BufferStrategyPaintManager.java:295) at javax.swing.RepaintManager.paint(RepaintManager.java:1106) at javax.swing.JComponent.paint(JComponent.java:988) at java.awt.GraphicsCallback$PaintCallback.run(GraphicsCallback.java:21) at sun.awt.SunGraphicsCallback.runOneComponent(SunGraphicsCallback.java:60) at sun.awt.SunGraphicsCallback.runComponents(SunGraphicsCallback.java:97) at java.awt.Container.paint(Container.java:1727) at org.netbeans.core.windows.view.ui.MainWindow.paint(MainWindow.java:530) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:725) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:670) at javax.swing.RepaintManager.seqPaintDirtyRegions(RepaintManager.java:650) at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(SystemEventQueueUtilities.java:128) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:598) ... regards JC.L
