REST client considers the wrong environment variable for `quarkus.rest-client."config-key".url`

[derkork]

Describe the bug

I have set an environment QUARKUS_REST_CLIENT__MY_CLIENT__URL variable set which is supposed to override the quarkus.rest-client."my-client".url at runtime. The quarkus.rest-client."my-client".url has a fallback setting in application.properties.

Expected behavior

The REST client uses the URL from the environment variable. This works in Quarkus 2.11.1, but does not work in Quarkus 2.12.2.

Actual behavior

This happens in Quarkus 2.12.2:

The REST client ignores the environment variablee and uses the fallback setting in application.properties. When I change the name of the environment variable to QUARKUS_REST_CLIENT_MY_CLIENT_URL (note the missing extra underscores for the ") then the value of the environment variable is used.

In Quarkus 2.11.1, everything works as expected.

@radcortez what is the proper value for the env var here?

[radcortez]

It should be QUARKUS_REST_CLIENT__MY_CLIENT__URL. Let me have a look.

[radcortez]

The issue here is that the KeyMap for recorded default values is not handling quoted keys correctly in certain API calls. I'll fix this.
