我制作了一个 Swing 小程序，它可以在 Eclipse 中毫无问题地运行，但是当我使用 Chrome 使用 html 文件运行它时，我得到一个运行时异常：java.lang.reflect.InvocationTargetException。任何人都可以建议有什么问题吗？这是我尝试过的：

  • 我已经读过 InvocationTargetException 包含了一些其他错误（导致它的另一个错误），但我不知道使用哪种方法来获取有用的错误 try{} catch(InvocationTargetException e){ e.toString()}。

  • 在线材料建议我使用 jdb 生成堆栈跟踪，但它似乎没有包含任何有用的信息来查找异常的原因：

问题是我在init()方法之外初始化变量。Eclipse 似乎对此没有问题，但使用浏览器Java 插件运行它会抛出java.lang.reflection.InterruptedThreadException.
