AutowiredAnnotationBeanPostProcessor.determineRequiredStatus(Annotation) throws NullPointerException if method wasnt found. [SPR-9364]

[spring-projects-issues]

Michal Troicki opened SPR-9364 and commented

If ReflectionUtils.findMethod return null we should return true instead invocation of the method fail with NullPointerException.

protected boolean determineRequiredStatus(Annotation annotation) {
		try {
			Method method = ReflectionUtils.findMethod(annotation.annotationType(), this.requiredParameterName);
			return (this.requiredParameterValue == (Boolean) ReflectionUtils.invokeMethod(method, annotation));
		}
		catch (Exception ex) {
			// required by default
			return true;
		}
	}

Hi Michal,

Can you provide more information about the use case that leads to a NullPointerException? A small reproduction project would be especially helpful. See instructions here: https://github.com/SpringSource/spring-framework-issues#readme
