Issue in lesson 31 (configuring qaurkus demo)

[MortenCroese]

Hi!
I'm in lession 31 and trying to open the config editor (http://localhost:8080/q/dev/) as in the demo.

But ... I get an internal server error.
java.lang.StringIndexOutOfBoundsException: begin 1, end 0, length 1
at java.base/java.lang.String.checkBoundsBeginEnd(String.java:4604)
at java.base/java.lang.String.substring(String.java:2707)
at io.quarkus.vertx.http.runtime.devmode.ConfigDescriptionsManager.calculate(ConfigDescriptionsManager.java:100)
at io.quarkus.vertx.http.runtime.devmode.ConfigDescriptionsManager.values(ConfigDescriptionsManager.java:59)

In the console I see:
2022-09-19 20:47:07,086 WARN [io.net.res.dns.DnsServerAddressStreamProviders] (build-35) Can not find io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider in the classpath, fallback to system defaults. This may result in incorrect DNS resolutions on MacOS.

Looking on the web, I saw a solution that didn't work for me (konveyor/tackle-pathfinder#190 It looked like the same issue except in the solution the "io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider" was { }).

I'm on an Apple M1. Using Java SE 17.0.4.1, GraalVM EE 22.2.0 and Apache Maven 3.8.6.

Please advice.

Solved it.

Used the previously mentioned solution but updated the classifier to the M1 chip (duh ;-) )

<dependency>
  <groupId>io.netty</groupId>
  <artifactId>netty-resolver-dns-native-macos</artifactId>
  <version>4.1.82.Final</version>
  <classifier>osx-aarch_64</classifier>
</dependency>
