Hello,
I tried to fix this problem by myself but finally I came here.

I'm upgrading my JEE application to JEE 10 which uses  namespace jakarta.
The deployment to Wildfly 38.0.0 in Ubuntu 24 works file.
But our production server is Debian 13 and somehow I got the error below.
There are any differences except the OS  which is Debian 13.
Even I treid to test on the Docker container which is built on Ubuntu 24 and wildfly 38.
The deployment works fine.
Is there any  issues on Debian 13. Is there anyone have these experiances?

Hi Jamie,

Not an expert, but what command do you use to start wildfly when it works (non-prod)? Are you using standalone.xml as the configuration or something like standalone-ha.xml which is typically oriented towards clustering? I would ensure that production environment is using the same command. I doubt it is OS specific -- I think you would have had problems long before getting a failed deployment if the OS were to blame.

Here's one more thing: compare the wildfly-server.log for non-prod and prod and see which subsystems are loaded (or not loaded).
