        Description


        File: list_conversion.js

        Arrays = java.util.Arrays;
        print(Arrays.asList("hello world".split(' ')));

        The above script works fine with jdk8u31 but fails on jdk8u40 early access build and jdk9 with the following stack trace:

        Exception in thread "main" java.lang.ClassCastException: Cannot cast jdk.nashorn.api.scripting.ScriptObjectMirror to [Ljava.lang.Object;
