JSON parser fails to parse JSON generated from HCL

[vetinari]

The following code fails:

package main

import (
    "encoding/json"
    "reflect"

    "github.com/hashicorp/hcl"
)

var hclData = []byte(`match "first" {
    type = "test"
    value = "first"
}
match "second" {
    type = "test"
    value = "second"
    match "inner" {
        type = "test"
        value = "third"
    }
}
`)

type Data struct {
    Matches []*Match `json:"match" hcl:"match"`
}
type Match struct {
    Type    string   `json:"type" hcl:"type"`
    Value   string   `json:"value" hcl:"value"`
    Matches []*Match `json:"match,omitempty" hcl:"match"`
}

func main() {
    var d, e *Data
    err := hcl.Unmarshal(hclData, &d)
    if err != nil {
        panic("failed to unmarshal hclData: " + err.Error())
    }
    jData, err := json.MarshalIndent(d, "", "  ")
    if err != nil {
        panic("failed to marshal into jData: " + err.Error())
    }

    err = hcl.Decode(&e, string(jData))
    if err != nil {
        panic("failed to parse jData: " + err.Error())
    }
    if !reflect.DeepEqual(d, e) {
        jd, _ := json.Marshal(d)
        je, _ := json.Marshal(e)
        panic("parsed data differs: \n" + string(jd) + "\n" + string(je) + "\n")
    }
}
