No I only checkout hotspot. That's the advantage of the "forest" 
approach - you only need to check out the repos you want to work on, 
everything else can be replaced in the build process either as an 
integral part of that build process (ie setting an import path for 
something), or by only building a sub component (eg hotspot) and 
manually dropping it into an existing JDK image.
