doc how to handle "Failed to load config value of type class java.lang.String for: some-key"

[maxandersen]

Describe the bug

https://quarkus.io/guides/lifecycle does not seem to mention anything about how users are supposed to handle
"Failed to load config value of type class java.lang.String for: some-key".

seems exception is recorded then never thrown and quarkus app just exits.

this doc should mention the existence of exitHandler argument on quarkus.run

Expected behavior

that docs mentions how users can handle the error and that exception is bubbled up for user to handle and exit code is not just 0.

Quarkus.run(hassq.class, (exitCode, error) -> {
            System.out.println("Exit code: " + exitCode);
            System.out.println("Error: " + error);
          }, args);

exit handler is called with exitcode and actual exception WITHOUT printing that "failed to load config value".

open questions: what happens if multiple errors?

and how to do exit in the handler?

calling System.exit(..) results in devmode failing to work.
