Hey guys
I finally found why some integration tests fail!
In scala 2.11.8 the REPL had been improved a lot. So the tests work well
with either scala 2.10 (with SparkJLineCompletion) or scala >=2.11.8 (with
cala.tools.nsc.interpreter.JLineCompletion).
I'll investigate further to see whether I find a solution for scala 2.11
<=2.11.7.
Otherwise I'll disable the (extended) tests for the scala versions below
2.11.8 (via Assume)
