Bug report: JavaScript arrays are not coerced into Java arrays when calling Java functions that expect arrays

[Tal Liron]

Lets say we have a Java class with this method:

class MyClass {
  void myMethod(String[] arguments) {}
}
And in Nashorn we call it like so:

myInstance.myMethod(['a', 'b', 'c'])

The JavaScript array seems to be converted into a string (as "a,b,c"), 
and then wrapped in a Java string array as its single element before 
sending to Java.

In Rhino, the above works as expected.
