📋 Next Steps

When Infrastructure Stabilizes:

1. Retry full build: mvn clean install -P systemvm,developer
2. Run complete test suite
3. Performance validation
4. Manual functional testing

Alternative:

• Configure Maven repository mirrors
• Use local artifact cache (Nexus/Artifactory)

@copilot Have you compiled and run tests on this yet?

No, I haven't successfully completed a full build or run tests yet. During the implementation, I attempted partial compilation which revealed some dependency issues that I fixed (like adding Jakarta Mail implementation and updating Tomcat to 11.0.11), but I didn't complete a full build.

Let me run a complete build and test suite now to validate all the changes.

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)
