#Java27

Java 27 is now available! #Java27 #JDK27 #OpenJDK Download now: Release notes: API Javadoc: Features: Blog:

Java 27 is here: 4 targeted updates + 5 previews/incubators. Collector changes, JFR enhancements, post-quantum TLS 1.3, and compact object headers (which cut memory usage). Details in the new post > #java #jep #java27 #development

Java 27 makes object headers smaller by default. My first thought: what if existing code needs those missing bits? I explain what changes, why ordinary Java code still works, and how to measure the savings. Diagrams + code examples. #Java27 #Java #JVM

#Java27 has arrived! 🥳☕ Get all the details about the latest release from our Java team.

Happy Java 27 release! ☕ On @java's launch stream, our founder @rdehuyss got 13 minutes to demo ClawRunr, an all-Java AI agent runtime. Live demo, sub-agents, MCP, one API key revoked right after. 🙈 Watch the full Java 17 webinar here 👇 #Java27 #AIAgents #OpenSource

Java 27 staje się jeszcze lepsza dzięki Valentina Developer Network – nieograniczone serwery, obsługa wszystkich źródeł danych i ultraszybkie raporty. #jvm #java #java27 @polishjug

Does your Java application initialize expensive constants even if they’re never used? Java’s Lazy Constants let you create constants when needed. Check out my blog post: #Java27 #LazyConstants #Java

Java 27 API documentation is now available! As usual, we present it in classical style with frame-like navigation. Another advantage: On APIdia you can also browse internals if you need to. Link in the comments. #java #javadoc #java27 #openjdk #jvm #APIdia

Ahead of the Java 27 release on September 15, I’ve put together an overview repository covering all 9 JEPs, notable non-JEP changes, and runnable code examples. You can find the full breakdown and code here: #Java27 #OpenJDK

One more day until #Java27 releases. I've put together an overview repository covering all 9 JEPs, notable non-JEP changes, and runnable code examples. You can find the full breakdown and code here: #Java27 #OpenJDK

Download #Java27 from your favorite vendor from inside @intellijidea JDKs are added as they appear. #IntelliJIDEA <3 #Java

Thrilled to welcome Ron Veen to XtremeJ 2026! 🚀 Ron will walk through all nine JEPs in Java 27, explaining what they bring to the language, JVM, libraries, and everyday Java development. 👉 #XtremeJ #Java #Java27 #JDK #JVM

Running two service calls in parallel is easy. Handling the case where one fails without leaving the other doing useless work is less so. JEP 533 in #Java27 re-previews Structured Concurrency with updated exception handling. With the default StructuredTaskScope, a failed subtask cancels the scope and interrupts unfinished work, while join() reports the failure as an ExecutionException. Seventh preview.

Java 27 gets even better with Valentina Developer Network—ship unlimited servers, support all major data sources, and deliver ultra‑fast reporting. #java #java27 #JasperReports
