Containers It hangs on RuntimesSmokeTest#quarkusEncodingIssues

[Karm]

Steps to reproduce:

RHEL 9/CentOS 9:

$ mvn clean verify -Ptestsuite-builder-image -Dtest=RuntimesSmokeTest#quarkusEncodingIssues 
-Dquarkus.version=3.15.1 
-Dquarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-mandrel-builder-image:jdk-17 
-Dquarkus.native.container-runtime=podman 
-Drootless.container-runtime=true -Dpodman.with.sudo=true | tee log.log 

-Dpodman.with.sudo=false same, -Drootless.container-runtime=true same.

It correctly builds and starts Quarkus app and then it hangs in WebPageTester on

           try (Scanner scanner = new Scanner(c.getInputStream(), StandardCharsets.UTF_8)) {

in readBytes of FileInputStream. It is likely something stupid, but I don't see it right now.

I still don't have a fix, because when I run it in a debugger, it works :-) :-) :-)

i.e. the c.getInputStream() indeed contains the expected bytes the Scanner reads and all is fine.
If I don't use debugger, it hangs.
