JSON equals is inconsistent in comparisons

[ryanjdew]

JSON equals isn't always correct. See the following example:

xquery version "1.0-ml";

import module namespace test = "http://marklogic.com/roxy/test-helper" at "/test/test-helper.xqy";

let $json-string1 := '{
    "options":
    {
        "matchOptions": "basic",
        "merging": [
        {
            "propertyName": "ssn",
            "algorithmRef": "user-defined",
            "sourceRef":
            {
                "documentUri": "docA"
            }
        },
        {
            "propertyName": "name",
            "maxValues": "1",
            "doubleMetaphone":
            {
                "distanceThreshold": "50"
            },
            "synonymsSupport": "true",
            "thesaurus": "/mdm/config/thesauri/first-name-synonyms.xml",
            "length":
            {
                "weight": "8"
            }
        },
        {
            "default": "true",
            "strategy": "default-standard"
        }],
        "propertyDefs":
        {
            "properties": [
            {
                "namespace": "",
                "localname": "IdentificationID",
                "name": "ssn"
            },
            {
                "namespace": "",
                "localname": "PersonName",
                "name": "name"
            },
            {
                "namespace": "",
                "localname": "Address",
                "name": "address"
            }]
        },
        "mergeStrategies": [
        {
            "name": "default-standard",
            "algorithmRef": "standard",
            "maxValues": "1",
            "sourceWeights":
            {
                "source":
                {
                    "name": "SOURCE1",
                    "weight": "10"
                }
            }
        }],
        "algorithms":
        {
            "stdAlgorithm":{"namespaces":{}, "timestamp":{"path": null}},
            "custom": []
        }
    }
}'
let $json-string2 := $json-string1
return (
"JSONs equal: " || (try { fn:exists(test:assert-equal-json(xdmp:unquote($json-string1)/object-node(),xdmp:unquote($json-string2)/object-node())) } catch ($e) {fn:false()}),
"Strings equal: " || (try { fn:exists(test:assert-equal($json-string1,$json-string2)) } catch ($e) {fn:false()})
)

Output:

JSONs equal: false
Strings equal: true

I tested @ryanjdew example using @cskeefer changes, and the sample passes now (after updating the module namespace).

Going to close the issue now.
