It's hard to square these articles with the reality I see on the ground: our baseline memory usage for common types of Java service is 1 GB, vs 50 MB for Go. We do have a few mammoth servers at the top end in both languages though (e.g. 75 GB heaps)
The deploy JARs have 100+ MB of class files, so perhaps it's a function of all the dependencies that you "need" for an enterprise Java program and not something more fundamental.
These blog posts also present AOT as if its just another option you can toggle, while my impression is that it's incompatible with common Java libraries and requires swapping / maintaining a parallel compiler in the build toolchain, configuring separate rules to build it AOT, etc. I don't have actual experience with it though so I could be missing something.
