Just my 2c: Nashorn is the default javascript implementation since Java 8, so if users try just "JSR223", they'll have to use different syntax between "if controller" and "JSR223".
As far as I can see, JMeter does not bundle "rhino-223 wrapper", thus userŅ have no easy option to "stick with Rhino". >The Nashorn engine is twice as slow as Rhino initially, Any references? PS. The only case for using Rhino I see is "backward compatibility with old JMeter scripts when using Java 8". Vladimir
