Hi all,

Please review this small set of changes to the immutable collections to make the zero-size instances singletons. (JDK-8156079)

This also includes a couple other small optimizations (JDK-8169222) to change the expansion factor from floating point to integer, and also to avoid creating a single-use Random instance to compute the hash salt value at startup.
