What are the uses of jstat and what are its limitations? It is a Java virtual machine tool for monitoring statistics and captures metrics when the JVM is running without any pre-requisite instrumentation. In this article, find out how to launch jstat, what the data it generates means, and what tool you can use to analyze this data.
Find out the answers to some commonly asked questions about the differences between 32-bit JVM and 64-bit JVM in this article. You will learn all about things to consider when migrating between the two, which performs better, when you should ideally use either, and how to download each.
In addition to the short and long-term support releases of Java, there is now a third variant. Azul Systems has introduced the Medium Term Support (MTS) for its Java distributions. What is it all about?
In this article, learn about TornadoVM, a plug-in for OpenJDK for accelerating Java programing on heterogeneous devices. It allows developers to automatically and transparently run Java programs on heterogeneous hardware, without any required knowledge on parallel computing or heterogeneous programming models. Find out about its use cases.
At Machine Learning Conference 2019 in Munich, Christoph Henkelmann gave a talk about TensorFlow training on the JVM. We recorded the whole thing, and now you can watch it here (including slides) to learn all about how to combine a TensorFlow model with Java.
Are you Troubleshooting OutofMemoryError related messages? In this article, Ram Lakshmanan walks through four JVM arguments related to OutofMemoryError. Find out what heat dump is and what to do when presented with these errors in this helpful guide.
It can be frustrating to have a build break because of a tiny difference between development and production environments. This tutorial aims to provide you with the tools to get a truly self-contained build up and running so you can focus on what matters without worrying about external influences.
No matter how carefully they wrote their program, nearly every developer knows the dreaded NullPointerException all too well. The JVM points to the location of the problem, but not in as much detail as you might like. With JEP 358, Goetz Lindemaier and Ralf Schmelter propose a solution to this problem.
When is it best to run your application with fewer instances and large memory size, or a lot of instances with a small memory size? In this article, Ram Lakshmanan discusses the differences and pricing of each module and goes over two multi-billion dollar enterprise stories.
The OutOfMemoryError can be a real pain to troubleshoot, and it’s still done manually for the most part, even in this day and age. Ram Lakshmanan teaches you how to automate troubleshooting and identifying the root cause of this error.
Every Monday, we take a step back and look at all the cool stuff that went down during the previous week. Last week, we explored the new JAX Mag, Project Helidon 1.0, and Linkerd 2.2. Also, we explored the how Clojure and Kotlin are a great fit for the JVM, Jib 1.0 is ready for production, and more!
A new day, a new potential feature. How do you feel about extending the space of JVM type descriptors to include type operators? If everything goes well, this might soon become reality. Let’s have a look at the draft submitted by John Rose, JVM Architect at Oracle.
Project Loom was introduced last year and now the initial prototype is publicly available. The goal of this project is to add a new concurrency tool to the Java toolkit: fibers. Let’s have a closer look at this project.
Since summer is well upon us, how about taking a quick trip to exotic Madagascar to meet some sweet asity birds? Or, we can just build universally reusable web fragments on the JVM with Asity, a lightweight abstraction layer for various web frameworks on the Java Virtual Machine that makes the long-lived “Write Once, Run Anywhere” concept a fascinating reality!
