Tuning the heap size, GC tuning, etc. are often needed to avoid huge GC spikes out of the box. Not to mention performance is pretty meh compared to something like Go for applications where non-trivial compute is needed.
GC tuning should be trivial for every Java shop. Yeah I guess you can find use cases where Go is faster than Java but in that case if this matters I would go for Rust be because I like it more than Go.
