"How JEPs Drive Java's Evolution" with Alex Buckley [AtA]

<p>JDK Enhancement Proposals are OpenJDK's vehicle for documenting and communicating substantial changes of the Java language, its APIs, and the runtime but also the JDK project itself, for example when it comes to development processes. Their well-defined structure and the immense care that goes into writing them make them eminently readable and understanding them well is essential to understanding Java's development.<br /> <br /> In this "Ask the Architect" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Alex Buckley, the Guardian of the JEP process.</p>

"Java *is* Memory Efficient" with Ron Pressler [AtA]

<p>Java's use of memory, often chided for being excessive, is actually a strength as it trades more memory use for fewer CPU cycles. Java can only make this tradeoff due to its moving garbage collectors, something more memory efficient platforms often cannot. But what's the point in leaving available memory on the table if using it makes your program run faster? Efficient use of that resource wouldn't be to leave it untapped but to use it to speed up the program.</p> <p>In this "Ask the Architect" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Ron Pressler, Java Architect at Oracle.</p>

"Make Java Safer with Flexible Constructor Bodies" [IJN]

<p><em>Flexible constructor bodies were added to Java 25 with JEP 513. In this episode of the Inside Java Newscast Billy Korando will review the issues with how constructors used to work before Java 25, either forcing developers to write convoluted code, or in some cases undermining the safety and integrity of child classes. Billy will then cover how flexible constructor bodies address these issues and how Java developers can use them to write safer code and better designed applications.</em></p> <p><em>Make sure to check https://inside.java/podcast</em></p> <p> </p>

"How JDK 26 Improves G1's Throughput" [AtA]

<p>G1 is Java's default garbage collector in most environments, and its throughput has been considerably improved in JDK 26 by streamlining its write barriers. This conversation explores the background of that change and dives deep into regions, write barriers, concurrent marking, card tables, and how all that impacts throughput before eventually getting to the improvements made in Java 26, which lay further groundwork to G1 becoming the one and only default collector across _all_ environments.</p> <p>In this "Ask the Architect" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Stefan Johansson, Hotspot Garbage Collection engineer at Oracle.</p> <p>For more, check https://inside.java/podcast</p>

"Analyzing Crashed JVMs" [IJN]

<p><em>The Java tool <code class= "highlighter-rouge language-plaintext">jcmd</code> ("j command") sends diagnostic commands to the JVM, which will react by supplying the desired information: from finalizer queues to heap and thread dumps, from GC insights to virtual thread scheduler statistics. At the moment, this requires a running JVM, but once candidate <a href="https://openjdk.org/jeps/528">JEP 528</a> is adopted, a lot of that information can be seamlessly extracted from a crashed JVM's core dump, allowing easy post-mortem analysis.</em></p>

"Java Carrier Classes & Discussing Syntax" [AtA]

<p>Carrier classes are Project Amber's current idea to extend some of records' benefits to regular classes. Probably the most important among them is deconstruction, which would allow classes to participate in pattern matching and reconstruction. In recent weeks, there have been two mails to the Amber mailing list that describe that idea, and in this episode we discuss them both as well as the evolution between them. We also hear why syntax discussions often provide negative value and get a sneak peak at what will likely be the next Project Amber language feature.</p> <p>Just ahead of the JavaOne speakers dinner, Nicolai Parlog sits down with Brian Goetz, Java Language Architect in Oracle's Java Platform Group, for this "Ask the Architect" episode of the Inside Java Podcast.</p>

"Towards Better Checked Exceptions" [IJN]

<p>Java's checked exceptions are both an integral part of the language and one of its most contested features. Whether their introduction was a mistake and whether they should all be turned unchecked are frequently discussed topics but since the former is not overly relevant and the latter unlikely, this conversation isn't moving Java forward. Instead, let's talk about specific issues with checked exceptions and what could be done about them - from (entirely speculative) language changes to (marginally realistic) JDK/library evolution to stylistic changes.</p>

"LazyConstants in JDK 26" [IJN]

<p>Lazily initializing fields in Java is error-prone and undermines constant-folding. JDK 26 comes with JEP 526, which previews <code class= "highlighter-rouge language-plaintext">LazyConstant</code>, a type that lazily initializes a value through a given <code class= "highlighter-rouge language-plaintext">Supplier</code>. It executes that supplier at most once successfully and then assigns the value to a field annotated with <code class= "highlighter-rouge language-plaintext">@Stable</code>, which allows constant folding. This API is also a poster child for how OpenJDK develops and evolves features.</p>

"HTTP/3 in Java" [ATA]

<p>HTTP/3 is the next version of the internet's most important application layer protocol. But, somewhat surprisingly, it uses UDP (via the new QUIC protocol) instead of TCP/IP, which has implications for the number of initial round trips, HTTP version selection, and time to first byte, but also adoption and evolution. Java 26 supports HTTP/3 out of the box.</p> <p>Nicolai Parlog talks to Daniel Fuchs and Daniel Jelinski, both Consulting Members of Technical Staff at Oracle and OpenJDK committers, about Java's HTTP client. They start by briefly retracing its introduction in Java 11 and its support for HTTP/2 before diving deeper into HTTP/3 to learn about the motivation, technical underpinnings like the QUIC protocol, and challenges for its adoption before discussing its integration into Java 26</p> <p>Note: Sorry for the minor audio issues, thank you for your understanding.</p>

"Carrier Classes" [IJN]

<p>This episode presents Project Amber lead Brian Goetz's recent email "Data Oriented Programming, Beyond Records", wherein he describes plans to improve Java's data handling capabilities by introducing carrier classes, a generalization of records. Like them, carrier classes describe their state through a component list that defines the type's external API: accessors, a constructor, and matching deconstructor - this allows carrier classes to participate in pattern matching and reconstruction. Unlike records, the implementation of this API remains the developer's task although component fields offer a shortcut for the common case where the API does map to a field. Carrier classes don't have to be final (and can hence participate in inheritance) and neither do their fields (so they can be mutable data carriers).<br /> <br /> The email also mentions carrier interfaces, allowing records to be abstract as well as a relaxation of deconstruction patterns that make them more amenable to evolution of the matched type. This episode also briefly touches on Gavin Bierman's mail to the Project Amber mailing list that announces pattern assignments and constant patterns.</p>

"Java's Plans for 2026" [IJN]

<p>In 2026, Java keeps evolving: Project Valhalla is gunning for merging its value types preview in the second half of this year; Babylon wants to incubate code reflection; Loom will probably finalize the structured concurrency API; Leyden plans to ship AOT code compilation; and Amber hopes to present JEPs on constant patterns and pattern assignments. And those are just the most progressed features - more are in the pipeline and discussed in this episode of the Inside Java Newscast.</p>

"Integrity by Default" with Ron Pressler

<p>The Java runtime offers a host of guarantees like memory safety, type safety, encapsulation, and many more. What makes these aspirations actual guarantees is a property called "integrity". But there are a few mechanisms in Java that allow undermining integrity - some for good, some for less good reasons. Integrity by default states that all such operations need to be disabled by default. Today we discuss why that is so important, what the progress toward this goal has been, and what Java developers need to know to keep their applications going.</p> <p><a href="https://inside.java/u/NicolaiParlog/">Nicolai Parlog</a> talks to <a href= "https://inside.java/u/RonPressler/">Ron Pressler</a>, who is Java Architect at Oracle and, among other things, lead of Project Loom.</p>

"Efficient Initialization Using Stable Values" with Per Minborg

<p>The Stable Values API is a preview feature in Java 25 that allows developers to define immutable objects that are initialized at most once. It combines the flexibility of lazy initialization with the performance advantages of final fields.</p> <p>In this episode, Ana hosts Per Minborg, a member of the Java Core Library team at Oracle and co-author of JEP 502 on Stable Values. Per explains the concept behind Stable Values and how this approach addresses the drawbacks of eager initialization in Java. By deferring the creation of expensive resources until they are actually needed, Stable Values contribute to more efficient application startup. He also discusses the design process and specifics of the API, highlighting its benefits in multi-threaded environments—particularly its ability to ensure thread-safe, at-most-once initialization without the need for complex synchronization mechanisms.</p>
