Callbacks in bean lifecycle

I was just going through spring documentation for Lifecycle callbacks for a bean. For initialization callback the documentation recommends using @PostConstruct annotation instead of using the InitializingBean interface implementation as it couples code with Spring. Could someone please explain what they mean when they say coupling code with spring. I will share the link to the section i was going through here.

The @PostContruct annotation is not Spring-specific, but from Jakarta Annotations. This way, the core part of your code is not tied to Spring specifically, but could also work in a non-Spring environment, including any Jakarta EE implementation (see "Certified referencing runtimes" in the article), for example, GlassFish or WildFly.

Here is the relevant Javadoc from the Jakarta documentation: PostConstruct.

InitializingBean is pure Spring and will only work in Spring. @PostConstruct is ordinary Java 1.8. Sadly, from 9 it's dependent on javax.annotation:javax.annotation-api:1.3.2
