在上面的activator类中，我将(JPanel)graphpanel添加到(JPhannel)testFrame.getPanel1()中。然后，通过testFrame类中的一个按钮，我使用了removeAll()法并再次添加静态graphPannel，但我得到了下面的错误
当我调试它时，我看到GLcanvas失去了对等。我找不到解决办法

请切换到JOGL 2.3.1。然后，将"javax.media"替换为"com.jogamp"以避免任何编译错误。
从其父容器中删除AWT GLCanvas时，它将失去对等对象，并且其OpenGL上下文将被破坏。当使用这种画布时，这是不可避免的。如果这不是所需的行为，请切换到NEWT。
在某些特定情况下，在某些硬件上创建另一个上下文可能会失败。如果您仍然使用最新版本的JOGL获得相同的堆栈跟踪，请填写错误报告：http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing
