While developing an extension, if any error is thrown during initialization, the following misleading exception appears in the logs when running quarkus:dev:

Bump to this issue as well, I get this when trying to add an endpoint in a new class. Commenting out the new class resolves the issue.

I think that this error message is misleading.
I suspect that the problem is on the return type of some of your jax-rs method. I had a GET method returning Object, after changing the return type to Response the problem's resolved. Double check your rest return types.

I would agree with this, I am finding that if you have the objects in a library, this issue appears (and you lose openApi schema..) see my issue #6780
