Java 非法国家例外：这是什么意思？

有人能解释为什么我会出现以下错误吗

线程AWT-EventQueue-0中出现异常 java.lang.IllegalStateException:调用时对等方不存在 位于的IncremaseComponentCount方法 incremaseComponentCountContainer.java:3978 at java.awt.Component.addNotifyComponent.java:6917 at java.awt.Container.addNotifyContainer.java:2758 at javax.swing.JComponent.addNotifyJComponent.java:4743 at java.awt.Container.addImplContainer.java:1114 at javax.swing.CellRenderPane.AddImplCellRenderPane.java:106 at java.awt.Container.addContainer.java:410 at javax.swing.CellRenderPane.PaintComponentCellRenderPane.java:134 在 javax.swing.plaf.basic.BasicTableUI.paintCellBasicTableUI.java:2115 在 javax.swing.plaf.basic.BasicTableUI.paintCellsBasicTableUI.java:2016 java:1812 在javax.swing.plaf.ComponentUI.updateComponentUI.java:161处 javax.swing.JComponent.paintComponentJComponent.java:778 at javax.swing.JComponent.paintJComponent.java:1054 at javax.swing.JComponent.paintooffscreenjcomponent.java:5221 at swing.BufferStrategyPaintManager.paintBufferStrategyPaintManager.java:295 javax.swing.repaitmanager.paintrepaitmanager.java:1206 at javax.swing.JComponent.\u paintImmediatelyJComponent.java:5169 at javax.swing.JComponent.paintImmediatelyJComponent.java:4980 at java:770 在 java:728 在 java:677 在javax.swing.repaitmanager.access$700Repaitmanager.java:59 at java:1621 位于java.awt.event.InvocationEvent.dispatchInvocationEvent.java:251 在java.awt.EventQueue.dispatchEventImplEventQueue.java:705 at java.awt.EventQueue.access$000EventQueue.java:101 java.awt.EventQueue$3.runEventQueue.java:666 at java.awt.EventQueue$3.runEventQueue.java:664 at 位于的java.security.AccessController.doPrivilegeEdNative方法 java.security.ProtectionDomain$1.doIntersectionPrivilegeProtectionDomain.java:76 在java.awt.EventQueue.dispatchEventQueue.java:675 at java.awt.EventDispatchThread.pumpOneEventForFiltersEventDispatchThread.java:211 在 java.awt.EventDispatchThread.PumpeEventsforFilterEventDispatchThread.java:128 在 java.awt.EventDispatchThread.PumpeEventsForFilterEventDispatchThread.java:121 WaitDispatchSupport$2.runWaitDispatchSupport.java:182 WaitDispatchSupport$4.runWaitDispatchSupport.java:221 位于java.security.AccessController.doPrivilegeEdNative方法

我猜你有一些线程问题。您是否有可能覆盖错误的addNotify

你能把代码片段添加到它发生的地方吗？在抛出错误之前，哪些值包含您的变量？您应该让他们设置断点并使用调试器。看起来您正在与GUI交叉线程。您是对的。但是我只在Java1.7中看到了这个问题，在1.6中我没有看到这个问题。
