Java at Microsoft

Introduction As cloud-native architectures scale across thousands of containers and virtual machines, Java performance tuning has become more distributed, complex, and error-prone than ever. As highlighted in our public preview announcement, traditional JVM optimization relied on expert, centralized operator teams manually tuning flags and heap sizes for large application servers. This approach simply doesn’t scale The post From Complexity to Simplicity: Intelligent JVM Optimizations on Azure appeared first on Microsoft for Java Developers.

Today we are announcing the Public Preview of the Azure Command Launcher for Java, a new tool that helps developers, SREs, and infrastructure teams standardize and automate JVM configuration on Azure. The goal is to simplify tuning practices and reduce resource waste across Java workloads. JVM Tuning in a Cloud-Native World Before the rise of The post Announcing the Public Preview of Azure Command Launcher for Java appeared first on Microsoft for Java Developers.

GitHub Copilot is taking a major step forward with expanded, deeply integrated support for JetBrains and Eclipse — bringing a new generation of agentic, intelligent capabilities directly into your favorite Java IDEs. This release strengthens Copilot’s cross-IDE experience, unifies agentic workflows, and unlocks more powerful automation to help developers code faster, modernize confidently, and stay The post Introducing Major New Agentic Capabilities for GitHub Copilot in JetBrains and Eclipse appeared first on Microsoft for Java Developers.

Technology is accelerating faster than ever, and developers are once again at the helm, shaping the future of applications, intelligence, and enterprise systems. With the rise of large language models (LLMs), agent-oriented architectures, and AI-driven development paradigms, Java developers find themselves in a uniquely powerful position to modernize code already powering critical systems, and to The post JDConf 2026 Is Coming With Modern Solutions for an Agentic World appeared first on Microsoft for Java Developers.

With the enhanced capability of the MCP on JetBrains, you can now bring prompts, resources, and even interactive tools directly into your IDE interacting with MCP. This means more flexible workflows, deeper context, and smoother collaboration between Copilot and your coding environment.  Let’s take a look at what you can do today with MCP Sampling, The post Unlocking MCP in JetBrains: How Copilot Uses Sampling, Prompts, Resources, and Elicitation appeared first on Microsoft for Java Developers.

Last Friday I was reviewing our backlog items in the Java Engineering Group, and found an idea we had when Log4Shell happened. To this day, there is still no main stream solution to “find in production where a given JAR is being used“. Why runtime truth matters (Log4Shell) When Log4Shell hit, lots of teams hunted The post Building a Runtime JAR inspector in 10 hours appeared first on Microsoft for Java Developers.
