@franckcuny I think it is a transient error. The tests passed on travis-ci
but failed on apache jenkins ci.
btw, for now, every pull request will be validated on both travis ci and
apache jenkins. so if one passed it, it typically means it is a transient
failure and should be good. we are only concerned if both of them failed.
