This Heads-Up is part of the regular communication sent to the projects involved, it covers JEP 472's preparation of restricted access to native code through JNI and the FFM API.
Now that Java 24 is features complete (Rampdown Phase One at the day of writing), it’s time to walk through all the functionalities that bring to us, developers, this new version. This article is part of a series on what’s new on the last versions of Java, for those who wants to read the others,
This article first appeared in Programmez! Hors série #16 (in french only). The Java Virtual Machine (JVM) is an execution environment that enables programs written in Java (or other languages compiled into Java bytecode) to run on different operating systems and hardware architectures. From the begining, the JVM was designed to be dynamic: it can
