  • GraalVM Java Compilers Join OpenJDK in 2023, Align with OpenJDK Releases and Processes

    The Community Editions of the GraalVM JIT and Ahead-of-Time (AOT) compilers will move to OpenJDK in 2023. They will align with OpenJDK releases and processes. Existing releases, GraalVM Enterprise Edition, and other GraalVM projects will not. GraalVM 22.3 provides experimental support for JDK 19 and improves observability. Project Leyden will standardize Java AOT compilation.

  • Java Champion Josh Long on Spring Framework 6 and Spring Boot 3

    Microservices show where Java lags behind other languages. Reactive programming provides a concise DSL to express the movement of state and to write concurrent, multithreaded code with better scaling. Developing in Spring Boot works well even without special tooling support. Josh Long is excited about Project Loom, Java optimization in Project Leyden, and Foreign-Function access in Project Panama.

  • Standardizing Native Java: Aligning GraalVM and OpenJDK

    Native Java is essential for Java to remain relevant in the evolving cloud world. But it is not a solved problem yet. And the development lifecycle needs to adapt as well. Standardization through Project Leyden is key to the success of native Java. Native Java needs to be brought into OpenJDK to enable co-evolution with other ongoing enhancements.

  • Go Native with Spring Boot and GraalVM

    Spring Boot 3 & Spring Framework 6, due in late 2022, will have built-in support for native Java. For Spring Framework 5.x & Spring Boot 2.x, Spring Native is the way to go. Spring Native provides integrations for Spring's vast ecosystem of libraries. It also has a component model that allows you to extend native compilation support for other libraries.

  • Article Series: Native Compilation Boosts Java

    Java dominates enterprise applications. But in the cloud, Java is more expensive than some competitors. Native compilation makes Java in the cloud cheaper. It raises many questions for all Java users: How does native Java change development? When should we switch to native Java? When should we not? And what framework should we use for native Java? This series provides answers to these questions.

  • Cloud Native Java with the Micronaut Framework

    The Micronaut framework provides a solid foundation for building Cloud Native Java microservices. It reduces the use of Java reflection, runtime proxy generation, and dynamic classloading. Tight integration with GraalVM Ahead-of-Time Compilation (AOT) has seen the usage of the Micronaut framework grow.  Active compilation-time checking increases type safety and improves developer productivity.

  • Native Java in the Real World

    Microservices on Kubernetes are the native Java sweet spot: they have the most significant framework and Java runtime overhead. Native Java needs more effort to build, debug, test, deploy & profile. The application framework should fully support native Java in production. Native Java adoption can be incremental. But a native Java application only works if all its libraries support native Java.

  • Kubernetes Native Java with Quarkus

    Quarkus is an industry leader in startup time and memory utilization for native and JVM-based Java applications. This reduces cloud costs. Kubernetes is a first-class deployment platform in Quarkus with support for its primitives and features. Developers can use their Java knowledge of APIs like Jakarta EE, MicroProfile, Spring, etc. Applications can be imperative or reactive - or both!

  • Revolutionizing Java with GraalVM Native Image

    GraalVM Native Image is an ahead-of-time compiler that generates native Java executables. These executables start very fast and use less CPU and memory. This makes Java in the cloud cheaper. GraalVM can even achieve peak throughput on par with the JVM. Many Java frameworks already support GraalVM, such as Spring Boot, Micronaut, Quarkus, Gluon, etc.

  • Article Series: Building Microservices in Java

    This article series will explore the state-of-the-art in building microservice-based architectures using the Java language. Alongside popular stalwarts, such as Spring Boot and Dropwizard, newer frameworks, such as Quarkus, Micronaut and Helidon, have been gaining momentum. These frameworks emerged after MicroProfile was introduced to the Java community in 2016.

  • Testing Quarkus Web Applications: Component & Integration Tests

    Quarkus is a full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation. Instead of reinventing the wheel, Quarkus uses well-known enterprise-grade frameworks backed by standards/specifications and makes them compilable to a binary using Graal VM. This article focuses on using some of the Quarkus testing facilities.

  • Java InfoQ Trends Report—September 2020

    This article provides a summary of how the InfoQ editorial team currently sees the adoption of technology and emerging trends within the Java space in 2020. We focus on Java the language, as well as related languages like Kotlin and Scala, the Java Virtual Machine (JVM), and Java-based frameworks and utilities.
