java - JFXPanel 安全异常

Question

我更新到 1.7.0_67-b01，现在看来我无法在我的 swing 应用程序中嵌入 JavaFX 面板。这是我得到的异常(exception)。有人知道解决方法吗？

Answer 1

您应该修改策略文件 ($JAVA_HOME/jre/lib/security/javaws.policy) 以包含写入此属性的权限。因此，您应该将此行添加到 javaws.policy:

permission java.util.PropertyPermission "javafx.macosx.embedded", "write";

好像是old bug
