Gang,
I reported to Rickard yesterday that strange thing happens in
activate() method (see expeption below), basically some form of
incorrect handling of Activatable (possibly Initalizable) interfaces
in the ASM generation code. Rickard's response was that "Well, this
should show up everywhere then...", and I think I have found the
actual problem. See below.
I am adding the following test to qi4j-runtime in 'develop' branch to
showcase the problem;
public class ComplexActivatableTest extends AbstractQi4jTest
{
public void assemble( ModuleAssembly module )
throws AssemblyException
{
module.addServices( SuperType.class );
}
@Test
public void validateThatApplicationGotAssembled()
{
ServiceReference<SuperType> reference =
serviceLocator.findService( SuperType.class );
reference.get().doSomething();
}
@Mixins( { DomainType.class, ActivationMixin.class } )
public interface SuperType extends Activatable, ServiceComposite
{
void doSomething();
}
public abstract static class DomainType
implements SuperType
{
public void doSomething()
{
System.out.println("Hedhman");
}
}
public static class ActivationMixin
implements Activatable
{
public void activate()
throws Exception
{
}
public void passivate()
throws Exception
{
}
}
}
