Not sure what you mean by this, as this has nothing to do with GC, and Java has had a multi-tier optimising compiler for 15 years now.

Go has much worse problems with GC than Java does these days, and nobody else is able to achieve similar performance in large programs with heavy workloads. So everyone else lives with less sophisticated compilers and memory management simply by accepting worse performance.
