I am "getting these things" from over a decade of working with Java. There are many good things about Java, especially when compared to C++. But the bad things will never get fixed if we pretend everything is perfect. I did say vtable dispatch was efficient, but I might not want to split my logic across classes. A chain of if-else is a linear scan and not efficient. Switch in its current form is too limited. It is well known that Java has no value types (there is a JSR). Even for a primitive type, the collection libraries need to box all values in order to abstract the element type. Every HFT user on Wall Street has had to write their own collections library using custom code generation to work around this.
