        File Name:      array-001.js
        Description:

        When accessing a Java field whose value is a java.lang.Array,
        or if a java method returns a java.lang.Array, JavaScript should
        read the value as the JavaScript JavaArray, an object whose class
        is JavaArray.

        To test this:

        1.  Call a java method that returns a java.lang.Array
        2.  Check the value of the returned object, which should be the value
            of the array.  Iterate through the array indices.
        3.  Check the type of the returned object, which should be "object"
        4.  Check the class of the object, using Object.prototype.toString,
            which should be "[object JavaArray]"
        5.  Check the class of the JavaArray, using getClass, and compare
            it to java.lang.Class.forName("java.lang.Array");
