Hmm... this error is a data structure corruption, the code is using a
DataStoreInfoImpl whose "catalog"
field is null, which should never happen.
We hear of this issue from time to time, but nobody ever managed to make it
reproducable, you just
reload the configuration or restart GeoServer and it's gone, without any
apparent way to make it surface
again... it's quite puzzling
