GeoWebCache/geowebcache — Issue #99: GeoWebcache throws 400 when GeoServer returns a 201
Author: iwillig
Created: 2012-01-27 23:01:26+00:00
State: open

It seems like GeoWebCache is returning a 400 and throwing a null point exception when GeoServer returns a 201. So GWC may consider this a successful response, but GeoServer does not provide an image in the response, hence the NullPoint Excpetion.

Please let me know if you need more information.

This is the GeoServer Stack trace.
