    JEP 451, Prepare to Disallow the Dynamic Loading of Agents, has been completed from Target status for JDK 21. This JEP has evolved from its original intent to disallow the dynamic loading of agents into a running JVM by default to issue warnings when agents are dynamically loaded into a running JVM.

  • JEP 444: Virtual Threads Arrive in JDK 21, Ushering a New Era of Concurrency

    JEP 444, Virtual Threads, was promoted from Candidate to Proposed to Target status for JDK 21. This feature offers a lightweight threading model to simplify the creation, management, and monitoring of high-throughput concurrent Java applications, allowing developers to efficiently handle millions of tasks and make better use of system resources.

  • SapMachine Vitals Provides Operating System and JVM Statistics

    SapMachine Vitals provides a monitoring tool that keeps a condensed history of operating system and JVM statistics. The feature is always on and may be used to retrieve information such as heap usage, Metaspace size, container memory statistics and limits, the number of classes loaded and the amount of threads spawned.

  • Static Java Current State: Compiled Native Executables for Startup Speed and Small Footprint

    Java’s long lasting motto of write once, run everywhere, seems to be adapting to the cloud native era. With the need for faster boot time and lower footprint, Static Java is gaining traction. To better understand the benefits and implications of adopting Static Java, InfoQ reached out to Dan Heidinga, principal software engineer at Red Hat.

  • Interview with Magnus Madsen about the Flix Programming Language

    Flix, an open-source programming language inspired by many programming languages, enables developers to write code in a functional, imperative or logic style. Flix looks like Scala, uses a type system based on Hindley-Milner and a concurrency model inspired by Go. The JVM language supports unique features such as the polymorphic effect system and Datalog constraints.

  • Service Overload Detection and Remediation at LinkedIn

    LinkedIn recently published how it handles overload detection and remediation in its microservices. Its solution, Hodor, provides an adaptive solution that works out of the box with no configuration. It is a platform-agnostic mechanism to run overload detectors and load shedders inside the monitored process that samples load and sheds traffic from within the application's processing chain.

  • GraalVM 22.0 Released with Native Image Improvements

    GraalVM, a polyglot virtual machine that provides a shared runtime to execute applications written in multiple languages, has released version 22.0 with many native image improvements. The native image builder utility comes with significant improvements to speed up build times, reduce image sizes, utilize less memory to build & run images, and provide deep insights into image generation process.

  • GraalVM 21.3 Supports Java 17

    Oracle Labs released GraalVM 21.3, featuring support for Java 17 and JDK Flight Recorder (JFR) for low-overhead production profiling of native Java executables. Compared to version 21.1 from April 2021, this release creates 14% smaller native executables for Spring PetClinic JDBC with 20% less build time. The release runs applications faster and begins to support the Java Platform Module System.

  • IBM Introduces the Semeru Runtimes for OpenJ9

    IBM introduced the no-cost Semeru Runtimes that use the class libraries from OpenJDK together with the Eclipse OpenJ9 Java Virtual Machine (JVM). The runtimes based on OpenJ9 may be used as an alternative for runtimes based on HotSpot. Previously AdoptOpenJDK produced binaries with OpenJ9, however, that’s no longer legally allowed since their move to the Eclipse Foundation under the name Adoptium.

  • Rookout Launches Live Logger to Dynamically Modify Log Verbosity

    Rookout, creators of Live Debugger, have launched Live Logger with the goal of making the wealth of information hidden in production logs more accessible. They intend to achieve that by dynamically switching the logging levels, log pipelining, log throughput tracking, text and context based filtering.
