Episode 32 “The Panama Effect” with Jorn Vernee

The Foreign Function & Memory API will be finalised in JDK 22, the FFM API helps you integrate native code within your Java program. Using this new API you can efficiently invoke code outside the JVM, safely access memory not managed by the JVM, call native libraries and process native data without the brittleness and danger of JNI.

Jorn Vernee, core contributor and maintainer of Foreign Function & Memory API, is Ana’s guest during this episode. Jorn explains what is Foreign Memory Access API, its goals and the iterations that this API went through. Jorn also shares a few examples of Java libraries that adopted the API, the performance improvements they observed. He also discusses how you can use this new API to integrate a native library within your own Java code.
