我正在开发一个 Eclipse E4 RCP 应用程序，我使用依赖注入。

我注意到，当 postconstruct 中存在运行时异常时，我在控制台中看不到该异常（它被吞没了吗？）。我确实看到了一个无法注入该类的异常。

因此，例如以下代码：

@Creatable
@Singleton
public class OurClass {
    @PostConstruct
    public void postConstruct() {
        System.out.println("PostConstruct Start");
        throw new RuntimeException("Test");
    }
}

public class OurPart {
    @Inject
    private OurClass ourClass;
}

给出以下输出：

PostConstruct Start
org.eclipse.e4.core.di.InjectionException: Unable to process "OurPart.ourClass": no actual value was found for the argument "OurClass".

有谁知道如何确保也显示运行时异常？
