Please advise a proper way of customization/tweaking of core Openfire classes.
I found the guide http://download.igniterealtime.org/openfire/docs/latest/documentation/overlay.html,
but I’m afraid it’s related to older versions of Openfire and isn’t relevant to 4.5.x anymore…
Was such a possibility (‘custom/source’) retired at all and I have to make changes directly in source codes with further rebuild, or I’m missing something?
Thank you in advance for your help!
