WebServer.builder() default socket configuration ignored

[ritzow]

Environment Details

• Helidon Version: Helidon Nima 4.0.0-ALPHA6 (see Maven config below)
• Helidon SE or Helidon MP: SE
• JDK version: Java 20
• OS: Windows 10

Problem Description

I expect that configuring the defaultSocket builder (through the below method or by directly using WebServer.DEFAULT_SOCKET_NAME to modify the default socket, but it does not appear to. If this is correct behavior, then there does not appear to be documentation documenting that certain default socket options cannot be configured.

Side note: It would be nice to be able to disable the default socket, or simply not have it automatically created in the first place.

Steps to reproduce

WebServer.builder()
    .defaultSocket(builder -> {
        try {
            builder
                .bindAddress(InetAddress.getByName("127.0.0.1"))
                .port(8080);
        } catch(UnknownHostException e) {
            throw new RuntimeException(e);
        }               
    })
    .build()
    .start();

Reassigning to @tomas-langer after discussion. He is planning an overhaul in this area with config-driven.

There is no such WebServerConfig.Builder#defaultSocket method nowadays in Helidon 4. Is this still an issue?.

Probably not, I've put it back in triage ; we will purge it next time we process triage issues.

There was a real bug at the time this was reported. The configuration should not be honored as expected. Closing this issue.
