Java Ecosystem buzz: Key Updates in Spring, Quarkus, Tomcat, and More

The Java landscape is constantly evolving, and this week brings a fresh wave of updates across several key frameworks and tools. Developers should take note of the latest enhancements and fixes in Spring Gprc, Quarkus, Apache Tomcat, and JReleaser.

Jdk Updates: Early Access Builds for Jdk 25 and Jdk 26

The latest early-access builds for Jdk 25 and Jdk 26 are now available, providing developers with a sneak peek into future Java features and improvements.
OpenJDK delivered build 30 of Jdk 25 and Build 5 of Jdk 26 this past week.

These builds incorporate fixes for various issues identified in previous versions. Detailed release notes are available for those looking to delve deeper into the specifics.

Spring Framework: Spring Gprc 0.9.0 Released

Spring Gprc 0.9.0 has arrived with notable changes focused on streamlining gRpc client and server configurations. A key update is the removal of the
GrpcClientFactoryCustomizer in favor of the more versatile
GrpcChannelBuilderCustomizer interface.

This new interface offers greater flexibility in customizing Gprc channel builders. Additionally, developers can now filter global interceptors and service definitions using instances of
InProcessServerBuilder.

Quarkus: Configuration Changes and Maintenance Release

Quarkus, the Kubernetes-native Java framework, has released version 3.24.2, its first maintenance release in the 3.24 series.This release addresses critical issues, including a
ClassNotFoundException in native mode when using custom implementations of Hibernate Orm’s
IdentifierGenerator interface.

The update also resolves a
ClassCastException encountered when using Jakarta Persistence’s
@EmbeddedId annotation with references to other entities in hibernate Reactive.

Pro Tip: Developers should migrate to the @ConfigMapping infrastructure to align with Quarkus’s future direction.

The Quarkus team has announced the sunsetting of legacy configuration classes,encouraging developers to adopt the new
@ConfigMapping infrastructure,which provides a unified system for building applications and extensions.

JReleaser: Simplifying Java Project Releases

JReleaser 1.19.0 is now available, offering enhancements to streamline the creation of Java project releases. A notable addition is the
yolo flag, which allows JReleaser to skip potentially misconfigured deployment or release sections.

Did You know? The yolo flag in JReleaser is designed to provide more control over the release process,allowing developers to bypass issues without halting the entire process.

The release also introduces a second
stagingRepository() method in the
MavenDeployer interface,accepting a Gradle
RegularFile instance as a parameter.

Apache Tomcat: Updates and Improvements

Apache Tomcat has released versions 11.0.9, 10.1.43, and 9.0.107, incorporating several key improvements and fixes. The default value for the
maxPartCount attribute in the
Connector class has been increased from 10 to 50 to address
FileCountLimitExceededException errors.

These releases also include multiple enhancements to HTTP/2, ensuring correct handling of data frames and removing an incorrect warning related to optional certificate verification.

Java News: Spring gRPC, Micronaut, & More – Staying ahead in the Java Ecosystem

The Java ecosystem is constantly evolving, with new frameworks, libraries, and features emerging regularly. Keeping up-to-date with these developments is crucial for any Java developer. This article delves into some of the most exciting recent news, focusing on Spring gRPC, Micronaut, and other java-related topics that are shaping the future of Java progress.

Spring gRPC: Integrating RPC Seamlessly

gRPC is a high-performance, open-source remote procedure call (RPC) framework that has gained meaningful traction in recent years, particularly for microservices architecture. the Spring framework,a cornerstone for Java developers,now offers robust integration with gRPC,streamlining the development of gRPC-based services. Understanding Spring gRPC is key to modern Java development.

Benefits of Spring gRPC

• Simplified Service Definition: Leverage Spring’s dependency injection and configuration to define gRPC services.
• Performance: gRPC, built on HTTP/2, offers significant performance advantages over traditional RPC and REST.
• Cross-Platform Compatibility: gRPC supports multiple languages and platforms, facilitating interoperability.
• Strong typing: Protocol Buffers (protobuf), used by gRPC, allows for strict data typing, enhancing code safety and maintainability.

Practical Tips for Spring gRPC integration

To successfully integrate Spring with gRPC, consider these practical tips:

1. Define Your Protobuf: Start by defining your service contracts and data structures using Protocol Buffers (.proto files).
2. Use Spring’s gRPC Support: Utilize the Spring gRPC libraries to generate code and configure your gRPC services.
3. implement Service Endpoints: Implement your gRPC service endpoints using familiar Spring annotations like @Service and @GrpcService.
4. Testing and Monitoring: implement robust testing strategies and leverage tools for effective monitoring of your gRPC services.

Micronaut Framework: Building Modern Java Applications

Micronaut is a modern, full-stack JVM framework designed for building modular, easily testable microservices and serverless applications. It differentiates itself through its compile-time dependency injection, resulting in faster startup times and reduced memory consumption. Micronaut’s architecture supports a rapid development cycle and focuses on delivering high-performance applications. The Micronaut framework is rapidly becoming a go-to choice for some Java developers.
