Could you please explain it a little bit more? When is that optimization applied, e.g. what conditions are required for this optimization, since which version of JDK/Hotspot it is supported, where it is implemented in JDK? When I take look at a product I'm working on, I see a lot instances of ArrayList$Itr objects, which are created by for-each loops (we use JDK 7u51). Thanks in advance! Best regards, Andrej Golovnin
