Stefan Richter commented on FLINK-8882:
---------------------------------------
Got to double check again, maybe the problem is also turning the WAL off,
again, for no obvious reason.
I don't think that a shared resource makes sense: there is only one write
options object ever created and owned per backend and this is managed along the
primary DB object - disposing always covers both.
