jgit is not able to follow "two step renames". A "two step rename" is a rename of a file using two commits: in the first commit the file is just copied to the new name/location, in a second commit, the original file is deleted. Example

Consider the following history:

A - B - C

Description of each commit

A file1 and file2 added

  git add file1
  git add file2
  git commit -m 'A'

B file1 copied to file11, file2 moved to file22

  cp file1 file11
  git add file11
  git mv file2 file22
  git commit -m 'B'

C file1 removed

  git rm file1
  git commit -m 'C'
  
Results using git:

$ git log --follow -- file22
B
A

$ git log --follow -- file11
B
A

Results using jgit:

$ jgit log --follow file22
B
A

$ jgit log --follow file11
B

(but not A)

git seems to follow copies and renames, while jgit just follows "real" renames.
