--------------------------------

Thanks for the patch. +1.

We actually made the same mistake in the scala code before: KAFKA-1469.

> org.apache.kafka.common.utils.Utils.abs method returns wrong value for 
> negative numbers.

> org.apache.kafka.common.utils.Utils.abs method returns wrong value for 
> negative numbers. The method only returns intended value for positive 
> numbers. All negative numbers except the Integer.Min_Value will be returned 
> an unsigned integer.
