The C++ code in modules/java-base should compile with headers of any Java 
but the Java code in the same module, more specifically the
"isolated" one, will NOT compile with java > 8 as (which is rare) some 
classes/interfaces have been removed (not just deprecated). So that is why 
we need opendjk8
to compile java code.

Let me send more detailed email later about it.
