Amazon Corretto 24 is now generally available

Corretto 24 is now available for download. Amazon Corretto is a no-cost, multi-platform, production-ready distribution of OpenJDK.

Corretto 24 is an OpenJDK 24 Feature Release, which will be supported through October, 2025.

OpenJDK 24 introduces enhanced performance with two new experimental features: the Generational Shenandoah garbage collector, designed to improve sustainable throughput, load-spike resilience, and memory utilization, and Compact Object Headers, designed to improve heap usage by shrinking object headers from between 96 and 128 bits down to 64 bits on 64-bit architectures. Additionally, this release includes Ahead-of-Time Class Loading & Linking, designed to improve startup time by making the classes of an application instantly available, Synchronize Virtual Threads without Pinning, designed to eliminate nearly all cases of virtual threads being pinned to platform threads, Quantum-Resistant Module-Lattice-Based Key Encapsulation Mechanism, designed to be secure against future quantum computing attacks. For more information about the features in OpenJDK 24, a detailed description can be found on its Project page. Amazon Corretto is distributed by Amazon under an open source license.
