-The payload will be encoded using a custom GSON config which encodes simple JSON keys into single characters. For instance, a payload of `{"className":"connection.ClientConnectionLoginPacket","packetId":1}` will be converted into `{"a":"connection.ClientConnectionLoginPacket","b":1}`. This seems to be a networking optimization and obfuscation tactic. The keys will always stay consistent and seem to be based on definition order; if a constructor of a packet lists the properties `id` and `type`, then you can always know that `a` will mean `id` and `b` will mean `type`. It seems that both parties always maintain packet definitions for both sides to decode recieved packets.

The keys will always stay consistent and seem to be based on the `@SerializedName` annotation, however commonly they're properly ordered in the constructor; if a constructor of a packet lists the properties `id` and `type`, then you can always know that `a` will mean `id` and `b` will mean `type`.
