RFR: JDK-8059135: New Nasgen dependencies to Nashorn breaks the JDK 9 build - bootstrapping problem?

[Erik Joelsson]

Hello,

Please review this small patch fixing the bootstrap problem of building 
nasgen. To make sure no other nashorn is picked up, force the 
bootclasspath to be only the rt.jar of the boot jdk and the newly 
compiled nashorn classes. This webrev also contains the anti delta of 
the workaround for this that was introduced in [1].
