Nashorn does not support implicit array conversion b/w script and Java array [ Re: some nashorn testing]

[A. Sundararajan]

Hi Andreas,

As I said in my last email, Nashorn does not support implicit conversion 
from JS array to Java array. You need to call Java.toJavaArray method to 
do the conversion. I've attached modified ObjectArray.java with this 
email -- both single dimensional and 2 D array need conversion. With the 
changed file, I get proper output

Thanks,
-Sundar
