Combine @Component and @ConditionalOnBean into one annotation

Question

I want to combine two Spring annotations into a single one.

More exactly I want to combine @Component and @ConditionalOnBean into one annotation named @SubComponent.

Is this possible?

What I have tried so far:

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Configuration
    @ConditionalOnProperty(prefix = "user", name = "property", havingValue = "true")
    @Slf4j
    static class TestableConfiguration {

        public TestableConfiguration() {
            log.info(getClass().getSimpleName() + " 666666 initialized");
        }

        @Component
        @ConditionalOnBean(TestableConfiguration.class)
//      @SubComponent(TestableConfiguration.class)
        static class Insight {
            public Insight() {
                log.info(getClass().getSimpleName() + " 666666 initialized");
            }
        }
    }
}

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Component
@ConditionalOnBean
@interface SubComponent {

    @AliasFor(attribute = "value", annotation = ConditionalOnBean.class)
    Class<?>[] value() default {};
}

but I am receiving an exception :

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [C:\Users\QV29YT\work\work_testing\2022_apr_27\demo\target\classes\com\example\demo\SubComponent.class]; nested exception is java.lang.IllegalStateException: Error processing condition on com.example.demo.SubComponent

Process finished with exit code 1

What I want to do is have something as the line commented, to create a bean if certain condition is meet.

Do you know if this is possible?

Or are there any other ways of handling this?

Edited after Alex's response:

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Component
@ConditionalOnBean(value = Object.class) // updated this
@interface SubComponent {

    @AliasFor(attribute = "value", annotation = ConditionalOnBean.class)
    Class<?>[] value() default {};
}

It seems that somehow Spring does a pre-verification if all things are in order.
