I did the same "Find Usages" twice, so i get two tabs in the Usages window. I clicked on the X (close window) of one and (fastly) clicked on the other one. I get this exception: java.lang.IndexOutOfBoundsException: Index: 1, Tab count: 0 at javax.swing.JTabbedPane.checkIndex(JTabbedPane.java:1562) at javax.swing.JTabbedPane.getMnemonicAt(JTabbedPane.java:1072) at javax.swing.plaf.metal.MetalToolTipUI.getAcceleratorString(MetalToolTipUI.java:141) at javax.swing.plaf.metal.MetalToolTipUI.getAcceleratorString(MetalToolTipUI.java:108) at javax.swing.plaf.metal.MetalToolTipUI.paint(MetalToolTipUI.java:73) at javax.swing.plaf.ComponentUI.update(ComponentUI.java:142) at javax.swing.JComponent.paintComponent(JComponent.java:742) at javax.swing.JComponent.paint(JComponent.java:1005) at javax.swing.JComponent.paintChildren(JComponent.java:842) at javax.swing.JComponent.paint(JComponent.java:1014) at javax.swing.JComponent.paintChildren(JComponent.java:842) at javax.swing.JComponent.paint(JComponent.java:1014) at javax.swing.JLayeredPane.paint(JLayeredPane.java:559) at javax.swing.JComponent.paintWithOffscreenBuffer(JComponent.java:4963) at javax.swing.JComponent.paintDoubleBuffered(JComponent.java:4916) at javax.swing.JComponent._paintImmediately(JComponent.java:4859) at javax.swing.JComponent.paintImmediately(JComponent.java:4666) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:451) [catch] at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(SystemEventQueueUtilities.java:114) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:461) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:163) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:157) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:149) at java.awt.EventDispatchThread.run(EventDispatchThread.java:110)
No line from NetBeans, probably JDK bug, but could you please attach the whole stack trace, or/and exception before this one? Thanks in advance.
The stack trace i sent is complete. There's nothing more than that in netbeans log. Cheers.
This is another version of famous JDK bug, see 75955 for details. *** This issue has been marked as a duplicate of 75955 ***
