Wrong error message

[jrm0695]

Consider this code :

class Test extends JSONObject {
    @required
    // @ts-ignore
    public prop1: String

    @required
    @array(String)
    // @ts-ignore
    public prop2: Array<String>
}

try {
    let test: Test = new Test({
        "prop1": "hello",
        "prop2": [5, 8]
    })
}
catch(e) {
    console.log("error " + e.toString())
}

I have the following error : Test.prop2 array element requires type 'number', got 'string' instead, while the error should be Test.prop2 array element requires type 'string', got 'string' number (confusing expected and actual array elements type)
