from GapList.java:get // A note about the inlining capabilities of the Java HotSpot Performance Engine // (http://java.sun.com/developer/technicalArticles/Networking/H...) // The JVM seems not able to inline the methods called within // this method, irrespective whether they are "private final" or not. // Also -XX:+AggressiveOpts seems not to help. // We therefore do inlining manually.

GapList.get inlines everything, including the rangechecks. ArrayList has two calls to functions.
