-------------------------------------------------------------------
[~chesnay] Thanks for pointing this out.
I added it to the classpath some time ago, because without it I was getting the
ClassNotFound exception, and a message saying that reporting would be turned
off.
It appears I forgot to set FLINK_PLUGINS_DIR. Fixed now.

Just tested it again without that jar:
