You can try using the present tag ex : <logic:present id="conflicts" name="ConflictResolutionForm" property="conflicts" type="com.pioneer.sales.terrmaint.demo.ConflictBean">
before actually going into the iterate and checkbox tags. This will check to see if the collection exists, before executing the logic inside the tag.

I found that if the array actually has data in it, everything works OK. It's only when it's empty or null that it blows up. Post if you find a solution and I will do the same. I am going to try to step through the source this afternoon.
