Apigee Edge for Private Cloud 4.54.00 drops Java 8 and standalone apigee-sso

In deployments with Apigee SSO enabled, an integrated OIDC identity broker in apigee-openldap replaces the standalone apigee-sso component and Apache Tomcat 9.0.x. Before upgrading, take a complete and validated LDAP backup; existing apigee-sso configurations do not migrate automatically. Deployments not using Apigee SSO require no action.

For migration prerequisites, validation checks, and rollback constraints, see Option 2: Upgrade UI (with Apigee SSO).

4.54.00 runs Java in mixed mode: Java 17 for Cassandra and ZooKeeper, Java 21 for the Management Server, Message Processor, Router, and Qpid Broker-J. Both Oracle JDK and OpenJDK are supported at those versions.

Oracle JDK 8 and OpenJDK 8 are no longer supported.

API proxies with custom JavaCallout policies or custom resource JARs can break on Java 21. For details, see Changes in Edge for Private Cloud 4.54.00.
