getChatRooms response JSON is not using correct names

[mikee805]

https://github.com/igniterealtime/openfire-restAPI-plugin/blob/master/src/java/org/jivesoftware/openfire/plugin/rest/entity/MUCRoomEntities.java has :

@XmlElement(name = "chatRoom") @JsonProperty(value = "chatRooms") public List<MUCRoomEntity> getMucRooms() { return mucRooms; }

therefore the JSON should produce an element chatRooms but what is produced is mucRooms:

1 < 200
1 < Content-Type: application/json
1 < Date: Sat, 09 Mar 2019 04:28:52 GMT
1 < Transfer-Encoding: chunked
1 < Vary: Accept-Encoding
1 < X-Frame-Options: same
{
"mucRooms": [{
"roomName": "test",
"description": "",
"password": null,
"subject": null,
"naturalName": "test",
"maxUsers": 1000,
"creationDate": 1552091703656,
"modificationDate": 1552091703656,
"persistent": true,
"publicRoom": false,
"registrationEnabled": false,
"canAnyoneDiscoverJID": false,
"canOccupantsChangeSubject": false,
"canOccupantsInvite": true,
"canChangeNickname": false,
"logEnabled": true,
"loginRestrictedToNickname": false,
"membersOnly": true,
"moderated": true,
"broadcastPresenceRoles": ["moderator", "participant", "visitor"],
"owners": ["admin@${HOST}"],
"ownerGroups": [],
"admins": [],
"adminGroups": [],
"members": [],
"outcasts": [],
"outcastGroups": []
}]
}

this is preventing the rest API client from correctly un-marshaling the JSON since it expects the element to be named "chatRooms" see: https://github.com/igniterealtime/REST-API-Client/blob/master/src/main/java/org/igniterealtime/restclient/entity/MUCRoomEntities.java

verified by removing the @xmlelement from the client entity.

However fixing this might just break other clients that are expecting "mucRooms".

This is probably a problem for all entities that rely on @JsonProperty for renaming.
