I am curious as to why Graal *build* needs to be done with JDK8 so that 
the resulting Graal compiler would be able to compile Java 8 class 
files? I believe Graal sources themselves do not (yet) use Java 8 features.

However, it appears to me that the need is more for bringing in the 
ability to parse and verify Java 8 class files (along with possibly the 
support for indy, what else am I missing?) so that the Graal compiler 
has the ability to compile Java 8 class files.
