Nexus bundle not getting called in Nexus 3.74 - 3.77

Hello.

As I understand, bundles have been deprecated for 3.78 and onwards.

But for Nexus 3.74 to 3.77 I cannot get Nexus to even call the the class that implements ContributedHandler.

My plugin is working fine in versions below 3.74, and I am getting zero errors in the logs when reacting to a package download through a normal CURL command.

Has there been any changes in the Nexus Repository after 3.73 that could cause this? I have roamed through the changelogs but I have found nothing that could have caused this.

In the UI you may want to check the Bundles UI and see if your plugin is properly resolved.

Yes, it is. But when CURLing a package, the handler of the bundle never gets invoked.
