Re: [jakartaee-platform-dev] Transitioning Jakarta EE to the jakarta namespace

Iâd like to see the reference implementation (GlassFish) tackle the name spacing first. How hard will it be for GlassFish to support both EE 8 and EE 9 (assuming 9 has a different namespace)? To me this debate has been somewhat abstract. The impact of the refactoring is going to depend upon application complexity. Some organizations are deploying multiple applications to containers (which by different groups on different schedules) which communicate via RMI etc.

This is one point of confusion not specific to this conversation, but GlassFish is not the reference implementation for Jakarta EE. There is no RI in Jakarta EE instead at least one vendor has to demonstrate compliance before a platform is approved.Â

Separately, I think the Java ecosystem is going through a bit of upheaval at the moment with getting code running on post Java 8. With Java 9, the technical debt bill came due. Do we want to throw a namespace challenge into the mix at the moment when companies are grappling with transitioning to Java 11?

This is a challenge, but we can't stifle innovation in the EE space because the SE space is innovating. We would be waiting forever for things to settle down, if they ever do, in the SE space.

ÂJust curious, why arenât the individual specs making the decision on when they jump to the new namespace?

That would be kind of crazy with some going to Jakarta EE and others sticking with javax? ÂAlso, remember that the javax namespace cannot evolve at all, so any active project where innovations are desired would be shooting itself in the foot to stick with the javax namespace. It needs to be a platform decision.
