Key JDK Enhancement Proposals (JEPs)
Language Features
JEP 530: Primitive Types in Patterns, instanceof, and switch (Fourth Preview): Helps developers increase productivity and streamline the development of applications that integrate AI inferencing by making Java more uniform and expressive. It eliminates multiple restrictions pertaining to primitive types that impose friction when using pattern matching, instanceof, and switch. To help developers further improve productivity, it also enhances the definition of unconditional exactness and applies tighter dominance checks in switch constructs, enabling the compiler to identify and reduce a wider range of coding errors.
Performance Updates
JEP 522: G1 GC: Improve Throughput by Reducing Synchronization: Helps developers process more work in less time by improving memory efficiency. It reduces the synchronization between application and garbage collector threads, increasing throughput with the G1 garbage collector. By running faster and supporting more users without additional hardware, Java improves efficiency, lowers infrastructure costs, and delivers a smoother user experience.
Project Leyden Features
JEP 516: Ahead-of-Time Object Caching with Any GC: Boosts developer productivity and resource efficiency by accelerating the start-up time for Java applications with any garbage collector (GC). It allows sequential loading of cached pre-initialized Java objects into memory from a neutral, GC-agnostic format. It also enhances the ahead-of-time cache, enabling the HotSpot Java Virtual Machine to improve start-up and warm-up time and be used with any GC, including the low-latency ZGC. This helps developers reduce application start up delays, scale their applications faster, and deliver better user experiences.
Libraries
JEP 500: Prepare to Make Final Mean Final: Helps developers improve application security and reliability by preventing unintended modifications, tampering, or accidental errors in critical business systems. It issues warnings about uses of deep reflection to mutate final fields and allows developers to mutate final fields where essential to avoid both current warnings and future restrictions. This crucial change enforces Java's "integrity by default" principle, which is focused on protecting sensitive data and business logic, reducing hidden risks, and lowering the chance of bugs or security vulnerabilities.
JEP 517: HTTP/3 for the HTTP Client API: Helps developers increase productivity by making it easier to write code that interacts with HTTP servers. It updates the HTTP Client API to support the HTTP/3 protocol, enabling libraries and applications to interact with HTTP/3 servers with minimal code change. By eliminating these common bottlenecks and enabling quicker data retrieval with reduced latency, it helps microservices and API-driven Java applications gain higher performance and more reliable network connections.
JEP 526: Lazy Constants (Second Preview): Helps developers increase productivity and resource efficiency by offering greater flexibility in the timing of their initialization, which is particularly valuable for AI and data-driven applications. Via a new API for lazy constants, which are objects that hold unmodifiable data, the JVM treats lazy constants as true constants to enable the same performance as declaring a field final. In addition, by enabling Java applications and their cloud native and AI-powered services to launch faster and use computing resources more efficiently, it helps developers execute agile and scalable deployments that lead to cost savings and a better experience for end users.
JEP 525: Structured Concurrency (Sixth Preview): Helps developers improve the maintainability, reliability, and observability of multithreaded code, which is especially beneficial for improving the scalability and resilience of AI and cloud native workloads. It simplifies concurrent programming via an API for structured concurrency, which treats groups of related tasks running in different threads as a single unit of work and helps reduce common risks arising from cancellation and shutdown, such as thread leaks and cancellation delays.
JEP 529: Vector API (11th Incubator): Helps developers improve the performance and cost efficiency of their Java applications by enabling them to deliver more insights and value with less hardware. The vector API expresses vector computations that reliably compile at runtime to optimal vector instructions on supported CPU architectures, which results in faster processing for data analytics, AI inference, and scientific computing workloads. This gives developers the ability to achieve performance superior to equivalent scalar computations often used in AI inference and compute scenarios.
Security Libraries
JEP 524: PEM Encodings of Cryptographic Objects (Second Preview): Helps developers improve productivity and enhance Java application security across widely used security formats via a new encoding API. The API encodes objects that represent cryptographic keys, certificates, and certificate revocation lists into the widely used, privacy-enhanced mail transport format, and decodes it back into objects. This reduces the risk of errors, simplifies compliance, and enhances the portability and interoperability of secure Java applications by streamlining cryptography setup and integration for enterprise, cloud, and regulatory needs.
Clean-Up Features
JEP 504: Remove the Applet API: Helps developers reduce their installation and source code footprints and improve the performance, stability, and security of applications by removing the Applet API, which was deprecated for removal in JDK 17 and is no longer part of the platform.
Additional Security, Reliability, and Performance Enhancements
In addition to the 10 JEPs, Java 26 offers dozens of updates that help organizations enhance application security, reliability, and performance. With Java 26, organizations can now streamline secure encryption with industry-standard hybrid public key encryption (HPKE), future-proof their supply chains with post-quantum ready JAR signing, and benefit from improved support for global standards with updates to Unicode 17.0 and CLDR v48. In addition, enhanced controls for cryptographic algorithms and legacy keystores further strengthen security and compliance, which helps organizations modernize with confidence.
Application performance and reliability are improved through dozens of additional updates that lead to faster JVM startup, more efficient garbage collection, expanded C2 JIT compilation, and smarter heap management. In addition, developers and administrators can increase productivity with new features including region-based file uploads in HttpClient, stricter runtime image building, an improved JVM metrics API, and a new dark mode for JavaDoc.
The features in the Java 26 release are a result of continuous collaboration between Oracle and members of the global Java developer community via OpenJDK and the Java Community Process (JCP). For more details on the features in Java 26, please read the Java 26 technical blog post.
