You are returning "Boolean.class" somewhere, but the actual content of 
the cell is a String.  That is *exactly* what the exception says. Your 
other program isn't updating the column with anything but a Boolean.

Make sure nothing in your code puts a String where it doesn't belong. 
Unit tests can be a helpful tool in that regard.
