[melloware]

Describe the bug

Same code in 2.16.6 and 3.0.0.Final I am not seeing the output from ServletContainerInitializer.

2.x Reproducer:
quarkus-servlet-2x.zip

3.0.0 Reproducer:
quarkus-servlet-3x.zip

run mvn quarkus:dev and watch the output.

2.x you see the ServletInitializer output:

3.x you see nothing:

Expected behavior

ServletContainerInitializer initializes and log messages appear.

Actual behavior

Nothing appears to be happening

How to Reproduce?

Run mvn quarkus:dev on both attached reproducers.

Output of uname -a or ver

Note I was just testing this bug in 3.0.0 to see behavior and its how I noticed this: #28028

[melloware]

I tested on Windows and Linux and the behavior is the same on both. so this can be untagged Windows it should be marked for Undertow.

Did you rename your service file? It should be META-INF/services/jakarta.servlet.ServletContainerInitializer. It's probably something we need to include in the migration recipe.

Yep that was it. Closing :)

I created https://github.com/quarkusio/quarkus-updates/pull/29/files .

It will be in the next version of the update (I have a few other tweaks planned).
