无法在apache camel中的处理器之间覆盖bean属性

@Component
@Scope("prototype")
public class MyBean {
    private String property;

    // getter and setter
}

from("direct:start")
    .process(exchange -> {
        MyBean bean = exchange.getContext().getRegistry().lookupByNameAndType("myBean", MyBean.class);
        bean.setProperty("new value");
    })
    .to("direct:nextStep");

from("direct:start")
    .process(exchange -> {
        MyBean newBean = new MyBean();
        newBean.setProperty("new value");
        exchange.getMessage().setBody(newBean);
    })
    .to("direct:nextStep");

@Configuration
public class AppConfig {
    @Bean
    @Scope("prototype")
    public MyBean myBean() {
        return new MyBean();
    }
}
