Can’t reproduce with a request that does not have a layer but has a style

http://localhost:8080/geoserver/topp/wms?service=WMS&version=1.1.0&request=GetMap&layers=&bbox=-124.73142200000001%2C24.955967%2C-66.969849%2C49.371735&width=768&height=330&srs=EPSG%3A4326&styles=polygon&format=image/png

 

The result is a good error message

<ServiceException code="org.geoserver.wms.map.GetMapKvpRequestReader">
No LAYERS has been requested

I checked all our logs but couldn't identify what the url was that caused the problem.

However I've just managed to replicate it with the following url:

http://localhost:8080/geo/dgmapping/wms?service=WMS&version=1.1.0&request=GetMap&layers=&styles=point

The problem is caused if there are styles specified and no layers.
