Steps to re-produce:

For the below GetMap request in XML format

<?xml version=“1.0” encoding=“UTF-8”?>
<ogc:GetMap xmlns:ogc=“http://www.opengis.net/ows”
xmlns:gml=“http://www.opengis.net/gml”
version=“1.1.1” service=“WMS”>
<StyledLayerDescriptor version=“1.0.0”>
<NamedLayer>
<Name>topp:states</Name>
<NamedStyle><Name>population</Name></NamedStyle>
</NamedLayer>
</StyledLayerDescriptor>
<BoundingBox srsName=“http://www.opengis.net/gml/srs/epsg.xml#4326”>
<gml:coord><gml:X>-130</gml:X><gml:Y>24</gml:Y></gml:coord>
<gml:coord><gml:X>-55</gml:X><gml:Y>50</gml:Y></gml:coord>
</BoundingBox>
<Output>
<Format>image/png</Format>
<Size><Width>550</Width><Height>250</Height></Size>
</Output>
</ogc:GetMap>

Make a POST request with workspace as part of URL.

curl -u admin:geoserver -H “Content-Type: text/xml” -X POST http://localhost:8080/geoserver/topp/wms --data @wms_post.xml

The request will fail with error message:

<?xml version=“1.0” encoding=“UTF-8”?><ows:ExceptionReport xmlns:xs=“http://www.w3.org/2001/XMLSchema” xmlns:ows=“http://www.opengis.net/ows” xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” version=“1.0.0” xsi:schemaLocation=“http://www.opengis.net/ows http://localhost:8080/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd”>
<ows:Exception exceptionCode=“NoApplicableCode”>
<ows:ExceptionText>java.lang.NullPointerException</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

The root cause:

The Null pointer error is being generated from https://github.com/geoserver/geoserver/blob/master/src/wms/src/main/java/org/geoserver/wms/WMSWorkspaceQualifier.java#L28

There is no NULL check on rawKvp in requests, which are NULL for XML payload based post requests.
