Plesae include the jitter value in the error message. It will be very useful for debugging

In StreamsGroupHeartbeatRequestManager and
AbstractHeartbeatRequestManager we use max.poll.interval.ms (default
300000) as the jitter value. Although RequestState.remainingBackoffMs
guards with Math.max(0, …), which won’t make the value become negative,
using a jitter that isn’t in (0–1) is unexpected.
In addition, we should validate that ExponentialBackoff receives a
jitter strictly within (0, 1) to prevent this scenario in the future.
