我是 Pax Exam 的新手，并试图通过调用我的 OSGI 服务来运行测试。在 Eclipse 中运行 paxexam 测试时出现以下异常。

任何想法为什么会发生这种情况？当我在以下代码中启用 @Inject DataGenerator 行时会发生这种情况。

@RunWith(JUnit4TestRunner.class)
@ExamReactorStrategy(AllConfinedStagedReactorFactory.class)
public class SampleTest{

    @Inject
    private DataGenerator dataService;

    @Inject
    private BundleContext bundleContext;

谢谢，拉胡尔

根据PAXEXAM-493，异常的根本原因是DataGenerator容器找不到您的服务。但是，通常 Pax Exam 会“很好地”报告此服务故障查找。在这种情况下，当 Pax Exam 尝试加载类ServiceLookupException以执行此操作时，ServiceLookupException自身的类查找失败（出于某种原因，Pax 开发人员尚未确定）。
