Java 15 will see the first release of Project Loom. I believe this will be a game-changer for the JVM. In this post, I’d like to dive a bit into the reasons that lead me to believe that. First, we need to understand the core problem. Then, I will try to describe how previous technologies try to solve it. Afterwards, we will see the approach taken by Project Loom. Finally, I’ll extrapolate on what effects the latter could have on the ecosystem.
