Hi.

Today I checked in JDK-8025435, which introduced a dependency between Nasgen and Nashorn: an import of jdk.nashorn.internal.codegen.annotations.SpecializedFunction.LinkLogic, which is a new public class. It previously imports jdk.nashorn.internal.codegen.annotations.SpecializedFunction; with no problem at all, so I thought everything would be fine, forgetting to do a full JDK 9 rebuild just after introducing this new class.

However the JDK 9 build breaks with Nasgen not being able to find this class:

make[2]: *** [jdk.scripting.nashorn-java] Error 2

My conclusion is that Nasgen imports its classes from some older bootstrapping version of nashorn.jar, and not using the one in the JDK. This is a build problem.

I've patched this temporarily by substituting the classes with their string descriptors in JDK-8059132, but I would prefer a real fix to this.
