JGit 4.4.0.201606070830-r

As part of the automated tests for the EGerrit project, we are cloning a repository from a locally hosted Gerrit server (running in a docker container). 
Things work most of the time, except when they don't :) and when they don't, they fail with the exception below.

We've verified that our repositories are properly closed and we don't really know where to go from here. Also we are thinking that it is not only us since a similar problem has been reported on the newsgroup (https://dev.eclipse.org/mhonarc/lists/jgit-dev/msg03146.html). 

If you have any ideas of where we could look for more details of where this fails, please let us know.
