OpenJDK is the free software version of Oracle's (or Sun's) JDK. It used 
to lack a few components to be buildable and runnable with only free 
software, and was a collection of separate components that were hard to 
build. IcedTea is a project to build a coherent collection of these 
components, and it also implemented a few missing components. IcedTea is 
only available for Java 6 to 8. From java 9, oracle did provide enough 
free software components and buildable sources, so we can build OpenJDK 
without a project like IcedTea.
