How to display runtime exception in postconstruct method in a Eclipse RCP e4 application?

Question

I am working on a Eclipse E4 RCP application and I use Dependency Injection.

I have noticed that when there is a runtime exception in the postconstruct, then I don't see that Exception in the console (is it swallowed?). I do see an exception that that class can't be injected.

So for example the following code:

@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;
}

Gives the following output:

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

PostConstruct Start

Does anyone know how to make sure the runtime exception is also shown?
