Please review JDK-8059132

[Marcus Lagergren]

For some reason the JDK9 relies on old nashorn.jars in the JDK when building Nasgen. This makes the JDK build of 9 crash when I started referring to a new Nashorn class. 
This is fundamentally an infra problem but in order for me to go to sleep peacefully I’m submitting a patch that makes the JDK build again. Please review:

(basically just using text instead of class references for type descriptors)
