java.lang.SecurityException:资源不可访问

我在访问JTable的单元格时收到此异常。当我单击第一个单元格并移动到第二个单元格时，就会发生这种情况。错误开始出现在Java7更新45中。在更新51中，错误不再出现，而是单元格锁定。下面是相当长的堆栈跟踪

因为我认为这与添加到java中的新安全措施有关，所以我尝试通过对所有JAR进行签名并添加适当的清单属性来使应用程序兼容。但这个问题仍然存在。任何想法都将不胜感激

你能把错误的代码发到哪里去吗？我不确定我能发什么具体的代码。它基本上是对话框中的JTable。我应该指出，当我的应用程序在我的开发环境中运行时，这个问题不会发生。它仅在编译和运行应用程序时发生（它是Java Webstart应用程序）。再加上这只是从Java 7 update 45开始的，而行为在update 51中发生了轻微的变化，这让我相信这是Oracle在其Java版本中添加的新内容所带来的一个更普遍的安全问题。看起来

JFormattedTextField

中的“value”类不是公共的，就是它的

（字符串）

构造函数不是公共的。谢谢Tom，根据您的评论，我能够找到问题所在。表的自定义单元格编辑器使用自定义JTextField，该字段使用私有内部类格式化程序。这些东西是在一系列构造函数中构建的。通过将格式化程序拉到一个单独的类中并创建在构造函数之外的JTextField中，问题消失了。
