a simple workaround is to change the last line

   var array;
   try {
     array = new (Java.type("java.lang.Object[]"))(len);  // array is Object[]
   } catch (x) {
     //array = [];                                        // array is NativeArray
     array = new (Java.type("java.lang.Object[]"))(0);    // array is Object[]
   }
