Proper ClassLoader with ClassShutter

[Sundararajan Athijegannathan]

By default Nashorn uses the thread context loader - which is usually
ClassLoader.getSystemClassLoader() [ which is the launcher loader ].

So,  your API call looks fine. What is the specific issue, if any,
you've in mind?

Thanks
