Is there a branch comparison bug in bitbucket server version 4.14 (self hosted with my organisatio)?

I can recreate a bug in this version, where the compare view doesn't properly display diffs between branches.

In the case where you have two branches with a common ancestor, but different subsequent commits, the diff screen will only show you the commits from the common ancestor onwards. 

e.g. I have 

master = c1,c2
branch1 = c1,c2,y1,y2
branch2 = c1,c2,z1,z2.

On comparing branch1 and branch2, for the diff i would expect to see the removal of y1 and y2 changes, and the addition of z1 and z2 changes.

The git diff command 'git diff branch1 branch2' produces the output I expect.

Hi @pjg,

You are spot on here.

Bitbucket Server performs the branch starting at the common ancestor. You can follow the conversation on this topic on this feature request:

- BSERV-7375

More details on how a Diff in Bitbucket Server is generated are also provided on the Understanding Diff view in Bitbucket Server page.
