Java doesn't sound right for your use case. Most programs written in Java works just fine without tracking memory, and if you have any issues you do a jvm memory dump to see which object types are taking up all that memory and then look at why they weren't collected.

Sure, I know that. But sometimes you don't have a choice because the decision was made years earlier by someone else, and you obviously won't rewrite a 1M LOC codebase.

Nevertheless, after spending a year writing Rust, I'd take Rust over Java for just any use case now, even including CRUDs and GUIs (actually doing a GTK GUI for a Rust app right now, and it is not any worse in terms of dev speed than Java Swing was, despite what people say about callbacks - I really don't mind an occasional Rc/Refcell/clone here and there).
