macos - 在 Mac 上切换到“镜像显示”后获取工具提示时，Mac Java 7 崩溃

Question

当 Swing 应用程序在双显示器机器上运行时切换“镜像显示”，然后立即覆盖具有工具提示的内容时，始终会出现可重现的崩溃。

我只在 OS X 10.8 上看到这个。我无法在 10.7 上重现它。

在 OS X 10.8（带双显示器）处于“显示镜像”关闭状态的 Mac 上针对 Java 7 编译和运行示例代码。
将鼠标悬停在 JLabel 上以查看工具提示
打开显示镜像。

再次将鼠标悬停在 JLabel 上，您应该会崩溃。

public class TestToolTip {
    public static void main(String[] args) {
        JFrame frame = new JFrame();

        JLabel label = new JLabel("hover");

        label.setToolTipText("tooltip text");
        frame.add(label);
        frame.setVisible(true);
        frame.pack();
    }
}

在关闭正在运行的应用程序上的笔记本电脑而不是“打开镜像”步骤时，我也看到了这一点。
