ArrayIndexOutOfBounds当我使用 Windows 远程桌面连接到运行我的应用程序的 PC 时，我的 Swing 应用程序似乎抛出异常。知道可能是什么原因造成的吗？

我在远程连接到 PC 时见过两次，但在其他情况下我从未见过。因为它都是Java 7u25 Sun JDK内部的（查看下面的堆栈跟踪），我什至不确定如何调试它。想法？

其他信息：机器有两个显卡，每个显卡都有两个显示器端口，Windows 配置为打开所有四个显示器。但是，当我远程进入机器时，显然只有一台显示器。带有开始菜单的监视器（以及包含应用程序的监视器）被 Windows 标识为监视器 #4。

Sun 的错误 JDK-4417798文档（您在上一条评论中提到的那个）描述了一种捕获异常的方法。引用文档：

public class BugHandler {
    public void handle(Throwable throwable) {
        if (e instanceof ArrayIndexOutOfBoundsException) {
           StackTraceElement[] trace = e.getStackTrace();

           if (trace.length > 1 
               && trace[0].getClassName().equals("sun.awt.Win32GraphicsEnvironment")
               && trace[0].getMethodName().equals("getDefaultScreenDevice")) {
              your_code_to_handle_exception();               
           }
        } 
    }
}

它还建议将-Dsun.java2d.noddraw选项设置为true. 根据this other document，它禁用了我们对 DirectDraw 和 Direct3D 的使用。看看是否有帮助。

您还可以尝试强制应用程序在特定屏幕上运行，而不是依赖 Java 对图形环境的自动检测。API 文档中有一个使用GraphicsDevice 类的相关示例。
