[Building Sakai] Assignment message

[Omer Piperdi]

We are seeing lots of message like this after upgrading our systems to 2.8.

2011-08-03 08:46:34,464  WARN http-8443-Processor23 
org.sakaiproject.assignment.impl.BaseAssignmentService - 
:getContentHandler:DefaultEntityHandler Long data parse problem nullnull

So far, I have not heard any complaint from our users but we are 
concerned about missing something here.. Any clue on these warnings?

Thanks
Omer
