cx_Oracle 6 causes a tests failures due to this change:
''Prevent closing the connection when there are any open statements or
LOBs and add new error “DPI-1054: connection cannot be closed when open
statements or LOBs exist” when this situation is detected; this is needed
to prevent crashes under certain conditions when statements or LOBs are
being acted upon while at the same time (in another thread) a connection
is being closed; it also prevents leaks of statements and LOBs when a
connection is returned to a session pool.'' (see cx_Oracle [http://cx-
oracle.readthedocs.io/en/latest/releasenotes.html#version-6-0-august-2017
release notes]).
