Introducing a large jar file (~63MB) in our software fails the git forensic plugin with an exception for calculating the delta:

The git repository itself handles the file without an issue.
Solution would be to exclude large files from the delta calculation (and consequently informing the user that the displayed information doesn't include all files) or to handle binary files in some other way (it is probably safe to assume that 99% of these cases are large binary files).
