>             Project: Kafka
>          Issue Type: Bug
>          Components: log
>    Affects Versions: 0.8.2.1, 0.9.0.0

>            Assignee: Jay Kreps
>             Fix For: 0.9.1.0

> now the code is :
> def read(position: Int, size: Int): FileMessageSet = {
>    ..... 
>     new FileMessageSet(file,
>                        channel,
>                        start = this.start + position,
>                        end = math.min(this.start + position + size, sizeInBytes()))
>   }
> if this.start is not 0, the end is only the FileMessageSet's size, not the actually position of end position.
> the end parameter should be:
>  end = math.min(this.start + position + size, this.start+sizeInBytes())
