Hi Andrea,
thanks for the reply!
I removed the footprints ( ;)! ) and it’s still the same problem. I also added
a new layer with a ImageMosaic Datasource – pointing to 0-Folder in the
pyramid. It’s still the same error – it only occurs if I am requesting a tile
size.
We will install the master tomorrow and test if the problem is solved. The
error message is quite different – plus we don’t have a color map in the sld
and we can’t view the layer in any other CRS.
Here are some pictures from my latest tests…
This is the index-shp (behind is the wms service):

Dear List,
currently I am facing a problem with our WMS Service. The data source is a big
Image Pyramid with 5 levels covering Germany in EPSG:25832. For tiles outside
the boundaries of the dataset Geoserver throws nullpointer exceptions:
2017-09-25 11:47:22,205 ERROR [geoserver.ows] -
java.lang.NullPointerException

I added a footprints.shp to each level of the Pyramid to set the boundary for
the WMS. Is this causing those issues? I added the footrpints via trial and
error, because I couldn’t find footprints for pyramids in the documentation.
I cannot tell if they are, but it's simple enough to remove the footprints,
reload the configuration, and check if that's causing the issue, no? :)
In terms of configuring footprints, a pyramid is really just a switcher between
N image mosaics, so you configure the footprints in each mosaic
separately. Footprints are designed to match each image in the mosaic and
provide a way to cut it to its valid area, there is no notion of footprint
for the whole mosaic. See documentation here:
http://docs.geoserver.org/stable/en/user/tutorials/imagemosaic_footprint/imagemosaic_footprint.html
The footprint is meant mostly for satellite/aerial imagery having each their
own "valid area", not sure if it's a match for you case
(I'm imagining you'd rather provide the boundaries of Germany for the whole
layer, but maybe I'm just guessing wrong).
We are running a geoserver 2.11.1 (we already downgraded, because in the latest
stable release (2.11.2) we couldn’t view the WMS in any other CRS)
For 2.11.2 I believe you hit this one, I tried a fix during the weekend but
could not
get any confirmation from the reporter:

Cheers
