Spring Cloud Config Empty array maps to empty string

Describe the bug versions:

spring-boot-starter-parent: 2.2.4.RELEASE spring-cloud-version: Greenwich.SR3

an empty array maps to an empty string rather than an empty array:

Sample fully reproducible example here (you will need to provide a config, example below)

The above sample code is about as simple as you can get. The config

test: []

maps to

{
    "name": "roomservices",
    "profiles": [
        "default"
    ],
    "label": null,
    "version": "b74cfaa653c789de331a25f8b9a2113303b1fecd",
    "state": null,
    "propertySources": [
        {
            "name": "${homehere}/IdeaProjects/config/roomservices.yml",
            "source": {
                "test": ""
            }
        }
    ]
}

It should instead map to "test": []

edit: my example code includes an objectmapper bean, but that is not required to reproduce the bug.

Does this still happen in Hoxton.SR6?

I'm still seeing this with Hoxton.SR6. Test branch: https://github.com/snowe2010/spring-cloud/tree/hoxton.sr6

I'm unable to replicate on Hoxton.SR10 or 2020.0.2, so looks like this got fixed in the meantime.
