Significant increase of Quarkus compiled binary after upgrade from 3.6.7 to 3.7.1

[vincejv]

Any one noticed a significant increase in the binaries compiled with 3.7.1 compared to 3.6.7? I'm using few Quarkus libraries on top of the framework, mostly just rest client related, and I have observed the docker image published in docker hub increased by 10mb+ (https://hub.docker.com/r/vincejv/qbittorrent-exporter/tags) 0.0.18 (37mb) vs 0.0.17 (28mb).

I thought removing support for older java version would actually reduce the binaries as it will remove legacy code?

Do you use Mandrel or GraalVM?

@zakkak could you help us get to the bottom of this one because I don't see any fancy dependencies/extensions?

    implementation 'com.google.code.gson:gson:2.10.1'
    implementation 'io.prometheus:simpleclient:0.16.0'
    implementation 'io.micrometer:micrometer-registry-prometheus:1.11.5'

    implementation enforcedPlatform("${quarkusPlatformGroupId}:${quarkusPlatformArtifactId}:${quarkusPlatformVersion}")
    implementation 'io.quarkus:quarkus-resteasy-reactive'
    implementation 'io.quarkus:quarkus-arc'
    implementation 'io.quarkus:quarkus-config-yaml'
    implementation 'org.jboss.logmanager:log4j2-jboss-logmanager'

So if we have a regression, it will probably hit a lot of users.

I created an issue here: #38600

@vincejv this is happening due to quarkus.locales being set to all in application.yaml. This results in all locales being included in the native image in Quarkus 3.7.1, which was not the case in 3.6.7.

A detailed answer can be found in #38600 (comment)
