would this make the build fail in case of a CS violation ? I'm not sure it is the best idea.

[jakoch]

Yes, this fails! But i could remove the .travis.yml modification from the pull request.

[Koc]

wow, finally Doctrine2 follows PSR2!

[jakoch]

Not yet. Lot's of work to be done before this happens. But it's time.
Please see https://travis-ci.org/#!/jakoch/doctrine2/jobs/2732759/L116

Please don't do this. Renaming a protected property is a BC break (for people extending the class) so it cannot be done until Doctrine 3

[stof]

and this is of course true for all protected properties in the codebase
