Worked on improving startup stability for the Keycloak repository in FIPS mode, focusing on cryptographic provider initialization and keystore management. Addressed a race condition by ensuring cryptographic providers were initialized before truststore configuration and registering BCFKS keystore types prior to truststore access. This approach resolved a NoSuchAlgorithmException encountered during startup in FIPS mode for version 26.6.1, reducing the risk of production regressions and supporting smoother upgrades. Added an integration test to verify FIPS-compliant truststore loading, enhancing reliability for secure deployments. Utilized Java, Quarkus, and integration testing to deliver targeted improvements in cryptography and system stability.
