# When running VerifiableProducer 0.8.X, both the current branch version and 0.8.X should show up because of the
# way verifiable producer pulls in some development directories into its classpath
#
# If the test fails here because 'ps .. | grep' couldn't find the process it means
# the login and grep that is_version() performs is slower than
# the time it takes the producer to produce its messages.
# Easy fix is to decrease throughput= above, the good fix is to make the producer
# not terminate until explicitly killed in this case.
