Oracle Releases Java 27 and Strengthens Post-Quantum Cryptography Support |
| [15-September-2026] |
New release delivers nine JDK Enhancement Proposals to boost developer productivity and improve application performance while strengthening Java's post-quantum cryptography and AI capabilities Release offers JavaFX 27 to help developers build interactive user experiences, and Helidon 27 for the development of lightweight microservices JDK 28 early access previews upcoming Java innovations, including Project Valhalla AUSTIN, Texas, Sept. 15, 2026 /PRNewswire/ -- Oracle today announced the availability of Java 27, the latest version of the world's number one programming language and development platform. Featuring thousands of performance, stability, security, and productivity improvements, Java 27 (Oracle JDK 27) provides a strong foundation for continued Java innovation. To help organizations prepare for more secure communications in a post-quantum world, Java 27 advances its post-quantum cryptography (PQC) capabilities with hybrid key exchange for TLS 1.3. Oracle is also highlighting JDK 28 early access (EA) to preview future innovations such as Project Valhalla. In addition, Oracle is announcing aligned updates across the Java ecosystem and Oracle Java Verified Portfolio (JVP), including Helidon 27 for lightweight microservices, JavaFX 27 for rich client applications, and Oracle Jipher 20, now part of JVP, to help customers deploy Java applications in FIPS 140-regulated environments. To learn more about Java 27, join the livestream at 10am CT on Tuesday, September 15th here.
"Java's security, reliability, and enterprise scale make it a critical foundation for AI agents that require trusted access to business systems and sensitive data," said Arnal Dayaratna, research vice president, software development, IDC. "Java 27's tools for AI development and post-quantum cryptography strengthen its role at the center of enterprise application development and help organizations prepare for a new generation of applications and security threats in the agentic era." "For more than three decades, Java has helped developers build powerful, reliable, and secure applications," said Georges Saab, senior vice president, Oracle Java Platform and chair, OpenJDK governing board. "Java 27 continues that proud tradition by providing a stable foundation for today's enterprise workloads and innovative AI and post-quantum cryptography capabilities. With Java 27, Oracle delivers a major post-quantum cryptography milestone and is executing on a roadmap to bring comparable capabilities to JDK releases with long-term support offered by Oracle. This will help customers protect business-critical applications and data with less disruption." Key JDK Enhancement Proposals (JEPs) Post-Quantum Security, Compliance, and Trust Features JEP 538: PEM Encodings of Cryptographic Objects (Third Preview): Helps to enhance the secure handling of widely used cryptographic material while improving interoperability with common security tooling and infrastructure. As a result, Java applications can integrate more easily with modern authentication, encryption, and certificate-management systems, helping support secure enterprise AI deployments. JEP 536: JFR In-Process Data Redaction: Helps troubleshoot production systems more safely by reducing exposure of sensitive information. This supports compliance, privacy, and security requirements while preserving the operational value of JFR diagnostics, which is especially relevant for AI-enabled systems that may process sensitive customer, employee, operational, or regulated data. AI, Data, and Modernization Features JEP 533: Structured Concurrency (Seventh Preview): Helps reduce development risk for cloud, microservices, and AI-enabled applications by enabling developers to build scalable, resilient services with fewer concurrency defects. This is relevant for AI workloads that coordinate many parallel tasks such as model calls, data retrieval, enrichment, ranking, orchestration, and real-time decisioning. In addition, by improving reliability, cancellation, error handling, and observability for multithreaded code, it helps developers accelerate their development projects. JEP 532: Primitive Types in Patterns, instanceof, and switch (Fifth Preview): Helps teams integrate AI inference into business logic faster and with fewer coding errors by making Java more uniform and expressive. This improves developer productivity and code clarity for data-heavy and decision-oriented applications, including AI, analytics, and event-processing workflows that use mixed primitive and object data. JEP 531: Lazy Constants (Third Preview): Helps improve resource efficiency by providing greater control over initialization timing while preserving performance and correctness benefits of constants. This can improve the user experience and reduce operating costs for AI applications where responsiveness, scalability, and resource efficiency are critical. Performance and Runtime Efficiency Updates JEP 523: Make G1 the Default Garbage Collector in All Environments: Helps simplify the migration and modernization of applications by giving developers predictable performance and operational consistency across deployment environments. This helps development teams run cloud, microservices, and AI-enabled Java applications with greater confidence and fewer environment-specific configuration differences. Additional Security, Reliability, and Performance Enhancements The features Java 27 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 27, please read the Java 27 technical blog post. Forward-Looking Innovations with Project Valhalla and Project Leyden Oracle is also advancing Project Leyden to improve startup time, time to peak performance, and memory footprint, including through ahead-of-time compilation. Together, Project Valhalla and Project Leyden show how Java continues to evolve through carefully designed platform innovation. Helidon 27 Helps Developers Build Fast, Lightweight Microservices
With Helidon 27, Helidon's version numbering and release cadence align with OpenJDK. Helidon is included in Java Verified Portfolio to give customers clearer support, compatibility, and upgrade planning. JavaFX 27 Helps Developers Build Rich, Interactive User Experiences JavaFX 27 helps improve performance, usability, and accessibility with a metal rendering pipeline on macOS, richer text editing controls, and continued accessibility enhancements. As part of Java Verified Portfolio, JavaFX is backed by Oracle commercial support, helping customers build and maintain modern Java user interfaces with greater confidence. Oracle Jipher 20 Helps Java Applications Meet FIPS 140 Requirements and is Now Included in JVP Supporting the Global Java Community with Innovations in the Cloud The Oracle Java SE Universal Subscription helps IT teams manage complexity, mitigate security risks, and contain costs by providing customers with best-in-class support. It now includes support for JVP, Java SE Subscription Enterprise Performance Pack, Java Management Service, portfolio-wide triage, and the flexibility to upgrade at a customer's pace. This helps IT teams manage complexity, mitigate security risks, and contain costs. To learn more about Java and its global ecosystem, please visit:
