Episode 68 “Operator Overloading with Type Classes” [AtA]<p>How OpenJDK's Project Valhalla is improving Java's support for custom numerical types.</p>
Read MoreAnnouncing Oracle Jipher 10.37: FIPS 140-3 Cryptography for Java
<p>Oracle Jipher 10 packages a FIPS 140-3 validated OpenSSL cryptographic module, making cryptographic services available through the standard Java Cryptography Architecture (JCA) framework.</p>
Read MoreValue Classes Still Need Compiler Sympathy
<p>Declaring a value class is first and foremost a semantic decision. It tells our fellow programmers that its instances are defined entirely by their state and do not need identity. That clearer model is valuable in itself! The JVM’s additional freedom to optimize how those values are represented is a welcome bonus. C2 can do amazing things with that freedom, but it cannot always recover information hidden behind abstraction boundaries. Profiling and inspecting the generated code remain the best ways to understand what is happening. To get the best results, we may still need to have a little sympathy for the compiler.</p>
Read MoreQuality Outreach Heads-up - JDK 28: Named Group Information Captured in the TLSHandshake JFR Event
<p>This Heads-Up is part of the regular communication sent to the projects involved; it covers that the named group information is included in the jdk.TLSHandshake JFR event.</p>
Read MoreEpisode 67 “Keeping Up With the Java Release Train” [I/O]
<p>Since Java moved to a six-month release cadence with JDK 10 in March of 2018, there has been a question if it was practical or possible for organization to keep up with such a release cadence.</p>

<p>Work on values progresses, JSON API incubation proposed to target 28, PQC in LTS, and more</p>
Read MorePreparing for Change: Safe Switching over Sealed APIs
<p>An exhaustive switch on a sealed type covers the permitted subtypes the compiler knows about; it does not cover future additions, which can cause MatchException at run time. API authors should document the expected evolution of sealed types so that client code can choose how to handle future additions. It is almost never necessary to use default when switching over a sealed type—and often not the best option.</p>
Read MoreEvolving a Java MCP Server During MCP Specification Upgrades
<p>Learn how a Java MCP server can embrace the latest MCP specification without breaking existing integrations or forcing immediate client upgrades.</p>
Read MoreThe Power of JDK Flight Recorder: Efficient Profiling and Troubleshooting for Java Applications
<p>Take a guided tour of the JDK Flight Recorder, the powerful event recording framework for the JVM. We'll cover the basics for getting started, show how to capture and analyze rich telemetry data, and demonstrate real-world workflows for investigating performance, memory leaks, threading issues, and more.</p>
Read MorePost-Quantum Cryptography in Long-Term Support JDK Releases
<p>Oracle is executing on a strategy to make post-quantum cryptography (PQC) broadly available across the Java ecosystem with a roadmap that brings standardized PQC algorithms and PQC-enabled TLS to current Long-Term Support (LTS) releases, helping reduce adoption friction for developers and enterprises.</p>
