I was just posting that I think I found the culprit... appengine-gcs-client seems to have a dependency on servlet-api:2.5:

Thanks a lot, you really helped me understand the problem better :) Drew On Thursday, 18 August 2016 18:31:23 UTC+1, JonL wrote: > > I don't use maven, so not 100% familiar with it.
