btw, that is the first exception I see. After that, I see different other
exceptions, but I suspect they are a consequence of this one
e.g.

Re: Release 2.7.1
Andy,
since your latest fix, I am running into another serious error I have not
seen before. It is possible that the problem is on our end - I will
investigate, but since I didn't touch any code, I am rather worried the
issue is related to your fix for 250.
I would rather have you hold off 2.7.1 and make sure things are ok.
I know you need test cases etc, but let me already provide a stack trace
to show the seriousness of the problem

Re: Release 2.7.1
Thanks for pushing forward on this Andy, I wish I had more time to do
stuff on Jena at the moment as there's bits and pieces that I'd like to
work on (e.g. Streaming parsing on SPARQL JSON, war-ifying Fuseki etc)
that I don't have the cycles for right now
Thanks for all the work
Rob
