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
@4000000050f28ef914f6a554 java.lang.NullPointerException
