All OpenJDK builds require access to the previously released
JDK 6, this is often called a bootstrap JDK.
The JDK 6 binaries can be downloaded from Sun's
<a href="http://java.sun.com/javase/1.6.0/download.html" target="_blank">JDK 6 download site</a>.
<a href="http://java.sun.com/javase/downloads/index.jsp"

For build performance reasons
is very important that this bootstrap JDK be made available on the
local disk of the machine doing the build.
