与菜单冲突相关的 Swing/SWT Java 错误

Question

我的开发人员为我更新了一个 java 应用程序，但在发送更新时忽略了包含 build.xml。现在，当我在 Eclipse (OSX) 中作为应用程序进行调试时，会弹出应用程序界面，但不可点击，并将以下内容返回到控制台

当我上次与我的开发人员交谈时，他说他会在几天后重新发送，但同时他说我可以使用以前版本的 build.xml 并删除 djswing 和 SWT来自 build.xml 文件，他说这导致了以前版本中的错误。

问题是除了引用这些的两行之外没有什么特别的。这是来自 build.xml 的代码

在运行程序时指定-XstartOnFirstThread 选项。这应该会在正确的线程上创建显示。
