[New Java Producer Kafka Trunk Branch ] Getting java.lang.IllegalStateException: Wrong condition: this shouldn't happen.

Hi Kafka Dev team,

I am getting following exception occasionally, and data is lost due to this
exception.    What could cause this error ?  We have prod release coming up
with New Kafka API end of this week.  So I any help is greatly appreciated.
