Chetan Mehrotra commented on OAK-3595:
--------------------------------------
bq. If a untested index configuration causes an exception in the index, then we
should add unit tests to ensure this can't happen.
Problem here is that at time of save we do not perform any validation as index
config is just content to the repository. Now once saved when it is interpreted
then causes failure. So there is no bug per se just that an invalid config is
causing the index to fail
