You don't compare two versions of OpenJDK in your article on stack
overflow. You compare a version of OpenJDK with a version of Oracle

OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
Java(TM) SE Runtime Environment (build 1.8.0_122-ea-b04)

As Phil already mentioned, Oracle JKD comes with a different, built-in
font renderer (called t2k) which is not part of OpenJDK.

There exist no official "OpenJDK early access" builds. You probably
refer to the builds from https://jdk8.java.net/download.html but
theses are actually Oracle JDK builds which contain the t2k font
renderer. So you compare t2k vs freetype!
