Description

We have noticed that there are failures due to :

1. Wrong parsing of new JDK version scheme (by calcite and cassandra dependencies like jamm). 10-ea vs 10.0.2
2. Cassandra startup timeout on Linux Jenkins CI server. Contrary to github travis CI (the one which validates PRs), it takes about 20s for embedded cassandra to start (still under investigation).
3. Sergey Nuyanzin reported that CassandraUnit leaves .toDelete folder in maven module folder (cassandra/) rather than target/ where all build and temporary files should be located. Not a failure but annoyance.
