Fix Linux CI port conflict in mvn clean install

[Copilot]

No code changes were made — the task was cancelled before implementation.

Investigation Summary

The mvn clean install failure on master is a Linux-only issue where step-04 fails to bind MariaDB to port 33328 (Address already in use). Windows and macOS CI jobs pass.

Root cause: Commit be36136 changed Java source/target from 1.8 to 17, which altered Surefire's fork behavior. Native MariaDB processes spawned during StandaloneUtilTest in step-03's test phase are not fully terminated before step-04 attempts to start its own MariaDB instance.

Failing log excerpt:

[ERROR] Can't start server: Bind on TCP/IP port. Got error: 98: Address already in use
[ERROR] Do you already have another server running on port: 33328 ?

Potential fixes (not yet implemented):

• Add a small delay or port availability check before step-04's MariaDB start
• Ensure Surefire properly kills forked JVM child processes via shutdown=kill configuration
• Use unique ports per module to avoid cross-step conflicts

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• mavenrepo.openmrs.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.12/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.12/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.12 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.12/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/openmrs-standalone/openmrs-standalone org.codehaus.plexus.classworlds.launcher.Launcher clean compile -pl pom-step-05.xml -am (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
