Defects related to the processing of this file - 

Defect #1 - the exception from a non-integer format is not very clean and contains a lot of information that is not really useful for troubleshooting. Can the exception be cleaned up and stated something like  "PersonID contains non-integer value - [UserName ] " or something to this effect.

Defect #2 - 

The requirement for skipping and continuing processing is not occuring. When an exception is thrown the process completely fails and no further processing is done. In this case - as you can see by the log above. Records #3 and #4 are never processed. 

In the case of record #3 this will be skipped since it contains a duplicate Person ID - this should be skipped and a message should be logged.
