Java Annotated Monthly – January 2022

Ida Bzowska

Welcome to the January edition of our monthly collection of JVM-related news! This is my first Java Annotated Monthly; I’m taking over this project from Irina and Trisha – if I can see a little further, it is because I’m standing on the shoulders of giants 😊.
