Hi guys,
we run quite a big Geoserver and recently have been struggling with a problem: now and then we get “java.lang.NullPointerException” thrown at us for no reason and the only thing that helps is restarting geoserver. I’ve asked for geoserver logs from our hosting and what I see is:
ERROR [wms.capabilities] - An error occurred trying to determine if the layer is geometryless
java.lang.NullPointerException
OR
