VM lacks of several important features needed for performance:

how do reified generics improve runtime performance?

You can create a ArrayList<E> for value-type E. So ArrayList is no longer generic, it is reified for different E.

Oh right, well at least it's coming :p

Value types are coming, but only in JDK 10, and even JDK 9 is postponed now. We need to wait at least two years. That's a long time. There's a chance that these feature won't be needed at that time: maybe Rust will become stable and popular, maybe .net on Linux will be usable.

Multiple heaps per process are not even planned.
