Jira issue originally created by user catchamonkey:
Within the constructor of Doctrine\Common\Annotations\FileCacheReader, it checks if the $cacheDir is writable, and if not, it throws an exception.
As this class performs read and write operations, it makes sense to only perform that check when it needs to write, maybe as part of the saveCacheFile method.
We are warming all parts of our cache during application build process, so on production servers we have no writable directories, this code means that can't happen.
