We've also found this with embedded builds. A slightly older JDK8 fails 
to build the latest sources. Normally it is something in langtools that 
causes the problem but I've never tried to find the cause, just do a 
fresh x86 build (using JDK7 bootstrap) then use that to bootstrap other 
builds.

IIRC there are parts of the build that act differently depending on 
whether your boot JDK is JDK7 or JDK8.
