[jgit-dev] unpacker error, clue

[Robin Rosenberg <robin.rosenberg@xxxxxxxxxx>]

Hi,

Gerrit (2.2) refuses to receive a push. Gerrit already has the rejected commit
on another branch. Does this information ring a bell? On the client side is
git version 1.8.0.msysgit.0. 

$ git push

But this works, i.e. the one where Gerrit refused. 

$ git push origin project/xxx

Possibly interesting piece in the server log:
