Java And Apache Camel: New Features
Java and Apache Camel's latest updates enhance performance, modernize compatibility with Java 17+ and Jakarta EE 10, and boost developer productivity through improved tooling like Camel JBang, advanced observability, streamlined configuration, and robust runtime integrations.
Java and Apache Camel: New Features
1 ) Apache Camel 4.9 Release Highlights
Introduced a startup condition feature for pre startup checks (e.g., environment variables or files existence).
Supervised route controller now emits RouteRestartingEvent for finer route failure tracking.
Added a “trust all” SSL certificate option for easier HTTPS setup in development.
XML/YAML route dump excludes nodes with default values for cleaner output.
Global data format configuration available in XML and YAML DSLs for easier reuse across routes.
Improved fluent builders in Camel Test to set expectations using Camel languages (JSONPath, XPath, JQ, Simple).
Camel JBang improvements: enhanced help output, extended export functionality (including Docker files for Spring Boot and Camel Main), and live error visibility in dev mode.
New Camel shell commands added for receiving messages, peeking queues, and interactive REPL mode.
2 ) Apache Camel 4 Major Updates
Migration to Jakarta EE 10 from javax for modern Java EE compliance.
Java 17 is now the minimum supported version, with plans to support Java 21 in upcoming LTS.
Dependency upgrades to latest versions ensuring better performance and security.
Internal routing engine optimized for improved performance.
Spring Boot 3.1 )2 integration updated to utilize embedded HTTP server directly, with initial support for native compilation (AOT).
Continued support enhancements for Quarkus and Camel Main standalone runtime.
Camel JBang now supports easily running different Camel versions, advanced commands for configuration, logs, tracing, and Kubernetes manifest exports.
XML DSL enhanced with unified bean configuration allowing inclusion of beans and routes in the same XML file and supporting Spring DI inline.
3 ) Apache Camel JBang Enhancements
Ability to specify and switch between multiple Camel versions quickly.
Commands for user configuration, running logs, message tracing, and sending messages to runtime integrations.
Detailed dependency resolution logs for troubleshooting.
Kubernetes support with manifest export and build support for container ready applications.
4 ) Observability Improvements
Introduction of camel observability services module to unify and harmonize observability configurations across different Camel runtimes.
Simplifies cloud management with opinionated default settings regardless of runtime choice.
5 ) Additional Features and Improvements
Camel Kubernetes support enhanced for multiple runtimes and k3s cluster type.
Fixes in Camel OpenTelemetry to address span leakage issues.
Route dumper improvements and trust all SSL for development convenience.
Overall, the latest Java and Apache Camel updates focus on modernizing platform compatibility, improving developer productivity with enhanced tooling (especially Camel JBang), boosting runtime performance and observability, and simplifying configuration across various Camel runtimes and deployments.
