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:

• www.w3.org
  • Triggering command: /usr/lib/jvm/temurin-21-jdk-amd64/bin/java /usr/lib/jvm/temurin-21-jdk-amd64/bin/java -Dnet.bytebuddy.experimental=true -jar /home/REDACTED/work/OpenPDF/OpenPDF/openpdf-html/target/surefire/surefirebooter-20260124034846705_38.jar /home/REDACTED/work/OpenPDF/OpenPDF/openpdf-html/target/surefire 2026-01-24T03-48-19_380-jvmRun1 surefire-20260124034846705_36tmp surefire_3-20260124034846705_37tmp (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)
