public class Chat
extends Object

A chat is a series of messages sent between two users. Each chat has a unique thread ID, which is used to track which messages are part of a particular conversation. Some messages are sent without a thread ID, and some clients don't send thread IDs at all. Therefore, if a message without a thread ID arrives it is routed to the most recently created Chat with the message sender.
