If you don't set a Garbage Collector for your #Java application, don't think the JVM will pick a good one for you either, no matter how many CPUs you give. 2 CPUs? 6 CPUs? It doesn't matter. If your container has less than 1792 MB and you don't set a GC, your app will use Serial

A Brazilian digital bank doesn't allow customers to transfer $17.99 due to a float rounding error. The UI and the backend asks customer to confirm if they want to transfer $17.98 instead. And then people wonder how important a software developer is to the business.
