The tooling is pretty easy to learn if scary looking at first and becoming a JVM expert, at least in the context of GC tuning, might take you a week or less. Some of the defaults are surprising though.

And I think there is some parallel with the kernel vs GC and mmap vs buffer pools - the GC simply has better context in the scope of the application. With other processes in the picture, though, yeah there is some provisioning complexity there.
