Hi, current implementations of the empty static factories (Map.of(), ...) delegate to static methods in java.util.ImmutableCollections. This indirection isn't really useful and adds a very small startup cost.
Bug: https://bugs.openjdk.java.net/browse/JDK-8221981 Webrev: http://cr.openjdk.java.net/~redestad/8221981/open.00/ Testing: tier1-2, verified a tiny improvement in startup profiles Thanks! /Claes
