我在使用 Rational Software Architect 8.0 时遇到问题。我正在开发一个为模型提供一些额外功能的插件。我正在尝试编写单元测试以确保我的插件按预期运行。

作为其中一些测试的一部分，我需要打开一个 UML 模型（emx 格式）并对其进行一些操作。我使用com.ibm.xtools.modeler.ui.UMLModeler.openModelResource(..)它，但它会引发一个奇怪的异常。这是代码片段：

Element root = null;
try {
    root = UMLModeler.openModelResource(fileName);
} catch (IOException e) {
    System.out.println("Error while opening model " + fileName + ": " + e.getMessage());
}
return root;

这是抛出的异常：

我显然做错了什么，但我不知道是什么。有什么建议么？

ModelResources 应该从 UMLModeler 的 EditingDomain 中打开：

UMLModeler.getEditingDomain().runExclusive(new Runnable() {
    public void run() {
        Element root = null;
        try {
            root = UMLModeler.openModelResource(fileName);
        } catch (IOException e) {
            System.out.println("Error while opening model " + fileName + ": " + e.getMessage());
        }
    }
});
