Spring - Bean executes method twice

The below method refreshDatasets is executed twice when I run the app. Any idea what I messed up with the configuration of Spring (annotation based)?

SchedulingTasks

@Component
@EnableScheduling
public class SchedulingTasks {

    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

    @Autowired
    public TestClass testclass;

    @Scheduled(fixedDelay = 1 * 60 * 60 * 1000)
    public void refreshDatasets() {
        testclass.simpleTest();
        System.out.println("The time is now " + dateFormat.format(new Date()));
    }
}

TestClass

@Component
public class TestClass {
    public void simpleTest() {
        System.out.println("FINISHED");
    }
}

Configuration

@Configuration
@ComponentScan(basePackages = "com.some.analytics.scripts",
excludeFilters = {@ComponentScan.Filter (
        type= FilterType.ANNOTATION,
        value=Configuration.class)})
public class ScriptsConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        PropertySourcesPlaceholderConfigurer p =  new PropertySourcesPlaceholderConfigurer();
        p.setIgnoreResourceNotFound(true);

        return p;
    }
}

Main

public class Scripts {

    public static void main(String[] args) {
        AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(ScriptsConfig.class);

        SchedulingTasks schedulingTasks = ctx.getBean(SchedulingTasks.class);
        schedulingTasks.refreshDatasets();
    }
}

When running the main method, I get the following output:

FINISHED The time is now 11:08:39 
FINISHED The time is now 11:08:39
