Java 26 adds HTTP/3, boosts G1 performance
Java 26 introduces native HTTP/3 support, 15% throughput improvements for the G1 garbage collector, and expanded AOT object caching. This release prioritizes modern networking and JVM efficiency while setting the stage for Project Valhalla's value types.
Java 26 is a high-performance floor-raiser that makes the JVM faster and more modern without requiring code changes.
- –HTTP/3 support via HttpClient finally brings modern QUIC-based networking to the standard library
- –G1 GC's new "card table" optimization delivers a rare 15% throughput win for heavy workloads
- –AOT caching improvements significantly cut startup times, making Java a better fit for serverless
- –Vector API (11th incubator) and final field integrity show the long-term commitment to high-performance AI/ML workloads
- –Removal of the Applet API cleans up decades of technical debt, streamlining the runtime
