These are breaking and significant changes which occurred in the span of just a single generation – the entire JDK had to be ported very quickly for compatibility. Its architecture differs drastically from the old Intel-based Macbooks. It has both a CPU and GPU on the same block. It’s their first RISC (Reduced Instruction Set Computing – and no pun intended). The M1 itself is an ARM-based SoC (System on a Chip). We also have several third-party open-source tools that rely on Java as well, most importantly for our various login integrations (Okta->DUO->AWS, OneLogin->WebApp, etc) that we need to be able to do just about anything for our jobs.Īnd so with this mix of a fresh M1, our required tooling, their dependencies, and our local development environment, the fun truly begins. This means we have to hunt and gather open-source Java to run our platform upon both locally and in the cloud. However, we do not run a paid/licensed Oracle JDK. No knock on that – it’s great hardware and it is extremely power efficient, requiring no fans whatsoever (finally, silence). I’m a senior engineer on the Java team, and it goes without saying that all my teammates need to quickly and reliably get a modern JVM running on their systems.Īll new hires are given M1 Macbook Pros. Recently I’ve been tasked with onboarding new hires for my current company.
