Neha Narkhede commented on KAFKA-569:
-------------------------------------

>> The problem with this is that since the creators of java hate all living 
>> things they made java.lang.Math.abs return a negative number when given 
>> Integer.MIN_VALUE (since it has no equivalent positive integer). Sooner or 
>> later hashCode() will return a negative value, which would cause this.

:O (Stumped and don't know what else to say). Great catch !

> logic dropped there. We should clean this up.
