An error occurs after adding my bot to the group.

[isul]

onGetUpdatesFailure:Unrecognized field "all_members_are_administrators" (class io.fouad.jtb.core.beans.Chat), not marked as ignorable (6 known properties: "last_name", "username", "title", "type", "first_name", "id"])
at [Source: {"ok":true,"result":[{"update_id":800563....

The following two classes seem to require some member variables.

Chat.java

@JsonProperty("all_members_are_administrators")
private boolean allMembersAreAdministrators;

Message.java

@JsonProperty("new_chat_participant")
private User newChatParticipant;

@JsonProperty("left_chat_participant")
private User leftChatParticipant;

Still not fixed, I'll make fork with fix of this problem.
