How to extend HtmlPageItemImpl.java in custom class

[pairx2]

Hi All,

Looking for some advice on how we can extend https://github.com/adobe/aem-core-wcm-components/blob/af5c4e8452a35e8c4a89b3b9b964ac8685c6dda5/bundles/core/src/main/java/com/adobe/cq/wcm/core/components/internal/models/v2/HtmlPageItemImpl.java in our custom class.

We don't want to copy paste the contents but rather inherit whatever is needed and override only those methods that need to be changed. Since this is internal class, bundle is not getting resolved if we simply extend the class.

Looking forward to some suggestions. @joerghoh, please can you advise.
