Priority: Medium Reporter: Peter Smythe (

)
This is due to a layer (in this case topp:states) pointing to a style
(pophatch) that no longer exists when the configuration is read from
disk/catalog.
Unfortunately there are no logs that indicate which layer causes this problem
and I had to view the Publishing page of each configured layer in order to
determine which layer was at fault.
Saving the layer (on any tab other than Publishing) fixes the problem on disk,
so the next time GeoServer reloads the problem is fixed.
