Helidon 27 brings restructured programming models, Messaging and Data JDBC modules

Oracle released Helidon 27, the first version under its Tip & Tail library model: the Tip tracks JDK 27 and the latest Java features, while the Tail is Helidon 4.5.5 on the JDK 21 LTS baseline. Helidon SE is replaced by Helidon Core with Imperative and Declarative models, plus new Helidon Messaging and Helidon Data JDBC modules.

• Helidon Core replaces SE with Imperative and Declarative programming models
• Helidon Messaging connects to Kafka, JMS and Pulsar without reactive APIs
• Helidon Data JDBC supports Jakarta Persistence, EclipseLink and Hibernate ORM
