Project Panama Key Features
Project Panama in Java 22 brings interoperability and performance enhancements:
- Java Native Interface (JNI) Replacement: Project Panama introduces the Foreign Function & Memory API (JEP 454), eliminating the need for JNI. This enables developers to directly call external code and access native data outside the Java Virtual Machine (JVM). This translates to greater flexibility, improved safety, and significant performance gains.
- Vector Processing: While still under development (JEP 460), the Vector API empowers developers to express vector computations. Compiling these computations to vector instructions on supported CPUs, unlocks substantial performance improvements compared to traditional scalar calculations.
