Breaking change in Coldfusion 10 vs Coldfusion 9

Here is one breaking change:

• DeserializeJSON of null value

Test Code to show the change:

result = deserializeJSON('{"test": null}');
writedump(result);
writeoutput(result.test);

In CF9, result.test is string value: "null".
In CF10, the above code will have error, because result.test is "undefined".
