Dec 1, 2025December 2025 — OpenLiberty/open-liberty: Stabilized startup and enhanced testing efficiency by tuning EDF session invalidation. Key outcomes: (1) EDF Server Startup Session Invalidation Delay Tuning: increased startup-time allowances across EDF servers and added startup-delay alarm monitors; updates across multiple server configuration files and monitors. Commits: 30acf2fdf24e928ad6c036b36be448123937feba; c4f81275927e094d820f38ad4d03e46dc61b3c73; 11920c7cac3f8c569cc43a735fa306268c65c856; 625195ed39293a8df0385d66c8b36d1b192bdd7c. (2) Testing Efficiency: EDF9 Immediate Session Invalidation: removed unnecessary delays for invalid sessions in the EDF9 test server configuration to enable immediate session invalidation; commit: 53542947c6b652df7644450d662031b5c8b8f83c. Major bugs fixed: startup instability caused by premature invalidation alarms; improved test accuracy by aligning EDF9 tests with immediate invalidation. Overall impact: improved startup stability, faster test cycles, and better monitoring signals. Technologies/skills: configuration tuning across multiple server files, monitoring integration, regression test optimization, version-control traceability.
