BinInterSedes comparator failing for tuple

Hello everyone

I recently updated my patch(PIG-2831) to work on the latest trunk and noticed that new trunk breaks my code. My code uses secondary sort on a tuple inside a databag. The issue seems to be related to BinInterSedes comparator. I have pasted the stack trace for reference. Can anyone let me know if this is side-effect of some other patch that is committed recently?
