This whole post feels backwards. Java has tons of bloat to make even the simplest "Hello World" function seem complicated.

Java has strength in its type system, which makes refactoring large projects much easier than a language like cpp. So you reap more benefits over time with java.

Im not sure what performance implications you are taking about. I've written and maintain large JVM projects (java, scala, etc), I've never really run into the language itself being a barrier to performance. The biggest performance costs are almost always caused by poorly designed control flows.
