### Motivation We found that sometimes `readPosition` is larger than `lastPosition`. If this happens, messages will not be consumed, messages will be backlogged, and recovery will not be possible. The reason for this problem is probably when executing `updateReadPosition` method. ### Modifications When executing the `updateReadPosition` method, the updated position is not allowed to exceed lastPosition+1 ### Documentation <!-- DO NOT REMOVE THIS SECTION.
