Hello!
I am trying to add a wfs build by ourself as a wfs-ng datasource. This
work just to the point when i try to create a layer from the datasource.
At this moment the following error occurs (full stacktrace as file):

this suggegst there is a missing (or perhaps unsupported) output format
somewhere in your capabilities file. I think while parsing the
describeFeatureType
see the location of the NPE:

When i add the wfs in QGIS everything works, also the getCapabilities
via browser. I am running geoserver 2.15.1 on tomcat9 (openJDK).
QGIS is not a validating WFS client so that does't mean anything.
In any case I would try with a supported version of geoserver or at
least the latest patch release before anything else.
