  • agent-gitops is updated to 1.1.10.
• The startup order of org.apache.felix.fileinstall is changed to start after org.apache.karaf.features.core:
  • This change avoids a boot-time race condition where FileInstall might truncate and temporarily empty a configuration file during rewriting, leading the Karaf features service to read an empty or partial configuration file.
  • By ensuring org.apache.karaf.features.core starts first, the features service reads its configuration before FileInstall has a chance to rewrites it, eliminating the race condition and preventing startup failures.
