 381      * Dave Adams (1-Nov-2016):

 383      * Ok.. I agree...weird title of the test-case. This test is focused on the isEqual equality
 384      * test within the NodeUtils helper class which compares the sorted structural paths of two Json
 385      * Object representations. I attempted to normalize unordered structures to produce an equality
 386      * result, as there doesn't seem to be any natural equality test between two JsonNode objects
 387      * that I could find to date.
 388      *
 389      * Basically, this test is confirming that if the same object values are present in different
 390      * orders, they are effectively the same Json Object representation, and pass, at least my
 391      * structural value equality test.
 392      *
 393      * I reordered the aaiEntityNodeDescriptors top level class types, and change the order of the
 394      * x,y coordinates to be y,x. Same values different order. Once again, the expectation is that
