AspectJ Pointcut not being triggered

Question

I'm trying to hook into Cucumber-Serenity libraries that are running using AspectJ but my pointcuts don't seem to be getting triggered.

SerenityAOP.java:

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

import gherkin.ast.Feature;
import gherkin.ast.ScenarioDefinition;
import net.thucydides.core.model.TestStep;
import net.thucydides.core.steps.StepEventBus;

@Aspect
public class SerenityAOP {    
    @Pointcut("execution(void cucumber.runtime.formatter.SerenityReporter.startOfScenarioLifeCycle(..))")
    public void beforeStartScenario() {}

    @Pointcut("execution(void cucumber.runtime.SerenityObjectFactory.stop())")
    public static void beforeStop(){}


    @Before("beforeStartScenario()")
    public void beforeStartScenarioAdvice(JoinPoint joinPoint) {
        Object[] signatureArgs = joinPoint.getArgs();

        Feature currentFeature = (Feature)signatureArgs[0];     
        String scenarioName = signatureArgs[1].toString();
        ScenarioDefinition scenarioDefinition = (ScenarioDefinition)signatureArgs[2];


        System.out.println("ASPECT: Starting test case for feature "+currentFeature+" with scneario: "+scenarioName);
    }

    @Before("beforeStop()")
    public void beforeStopAdvice() {
        boolean status = StepEventBus.getEventBus().aStepInTheCurrentTestHasFailed();
        String stepDescription = StepEventBus.getEventBus().getCurrentStep()
                .transform(TestStep::getDescription)
                .get();

        System.out.println("ASPECT: Testcase: "+stepDescription+" status = "+status);           
    }
}

But I'm not seeing my printlines anywhere during execution.

Is there some way I need to hook into these internal library calls differently? Or are my pointcut selectors wrong?

EDIT: Adding a comment in case the current answer gets removed

With the cucumber hooks I'm not able to detect when a new feature is started. I need to get the name of the feature and scenario when they each start. I haven't found a way to do that with event bus.
