Oracle reported the availability of Java 27, describing the release as part of its Java platform updates. The company said the update included post-quantum cryptography improvements and multiple JDK Enhancement Proposals covering security, performance, and features intended for AI and data workloads.
Oracle said Java 27 adds post-quantum cryptography capabilities for more secure communications, and it highlighted JDK 28 early access previews for future platform work such as Project Valhalla. The release also included updates across the Java ecosystem through Oracle Java Verified Portfolio, covering Helidon 27, JavaFX 27, and Oracle Jipher 20.
Oracle detailed nine featured JDK Enhancement Proposals. JEP 527 added post-quantum hybrid key exchange for TLS 1.3, JEP 538 provided PEM encodings of cryptographic objects, and JEP 536 added JFR in-process data redaction. For AI and data, JEP 537 introduced the Vector API (12th Incubator), JEP 533 covered structured concurrency, JEP 532 addressed primitive types in patterns, and JEP 531 implemented lazy constants. For performance and runtime efficiency, JEP 534 enabled compact object headers by default and JEP 523 made G1 the default garbage collector in all environments.
Beyond the JEPs, Oracle stated Java 27 included non-JEP updates that strengthened security through post-quantum cryptography, improved cryptographic performance, greater runtime visibility, and enhanced diagnostics. Oracle also said Project Valhalla’s first major release phase appeared in JDK 28 early access, and it advanced Project Leyden for startup time, time to peak performance, and memory footprint, including ahead-of-time compilation.
“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.”
