some nashorn testing

[Marcus Lagergren]

Remi, Andreas

I can't reproduce your problem running 

java -jar nashorn.jar script.js

where script.js is 

--
 var array;
 try {
   array = new (Java.type("java.lang.Object[]"))(len);
 } catch (x) {
   array = [];
 }
--

Do you have a reproducer you can send me ? I know there was a bug regarding array literal types just before Christmas, but it's in the openjdk as far as I can tell.

Regards
Marcus
