This quick fix should offer to delete @Interceptor/@Decorator annotation

Test case:

EXECUTE: Create CDI project
EXECUTE: Create SessionBeanAnnotatedDecoratorBroken class

package org.test;

import javax.decorator.Decorator;
import javax.ejb.Stateless;

@Decorator
@Stateless
public class SessionBeanAnnotatedDecoratorBroken {

}

ASSERT: Both annotations (@Decorator and @Stateless) should be marked by problem marker
EXECUTE: Point mouse to @Decorator or @Stateless annotation
ASSERT: Text hover with "Delete @Decorator annotation from 'SessionBeanAnnotatedDecoratorBroken' class" appears

EXECUTE: Create SessionBeanAnnotatedInterceptorBroken class

package org.test;

import javax.ejb.Singleton;
import javax.interceptor.AroundInvoke;
import javax.interceptor.Interceptor;
import javax.interceptor.InvocationContext;

@Interceptor
@Singleton
public class SessionBeanAnnotatedInterceptorBroken {
	@AroundInvoke
	public Object alwaysReturnThis(InvocationContext ctx) throws Exception {
		return ctx.proceed();
	}
}

ASSERT: Both annotations (@Interceptor and @Singleton) should be marked by problem marker
EXECUTE: Point mouse to @Interceptor or @Singleton annotation
ASSERT: Text hover with "Delete @Interceptor annotation from 'SessionBeanAnnotatedInterceptorBroken' class" appears
