When a single active consumer with an offset is closed while no messages have been consumed, the offset 0 is sent to the server when closing the consumer gracefully and auto commit is enabled.
Recently
lastStoredOffset
was changed to be initialized with -1 for #306 , however that change caused this bug because the offset is only sent whenlastStoredOffset < currentOffset
. Because currentOffset is set to 0 by default by offset next and the default 0 initalization,lastStoredOffset < currentOffset
is true when closing the consumer resulting in the offset 0 being sent. Because no messages were consumed either the offset was not populated.
