July 2026: Focused on improving test reliability rather than feature delivery. No new user-facing features were released this month. Major bug fixed: LibertyServer Component Test Java 2 Security State Tracking; corrected test logic to reliably track the Java 2 security state during resets and to set the startedWithJavaSecurity flag when Java 2 security is enabled and no checkpoint information is present. Commit b57c4848d8ee488f5fd41f43f94df141ebc659f3: 'Reset started with Java security flag when resetting started state'. This improves the accuracy of server state tracking in component tests. Impact: more reliable component tests, reduced false negatives, and better confidence in security-state transitions for release readiness. Technologies/skills demonstrated: Java, LibertyServer, test automation, component testing, state tracking, CI.
