NPE when CSS parameter "stroke-dasharray" is referenced from GML
----------------------------------------------------------------

                 Key: GEOT-2929
                 URL: http://jira.codehaus.org/browse/GEOT-2929
             Project: GeoTools
          Issue Type: Bug
          Components: core styling
    Affects Versions: 2.5.7
            Reporter: Jan Schroeter


Using the following (legal) SLD fragment results in a NullPointerException:

<Rule>
  <LineSymbolizer>
    <Stroke>

<CssParameter name="stroke-dasharray"><ogc:PropertyName>strokeDashArray</ogc:PropertyName></CssParameter>

    </Stroke>
  </LineSymbolizer>
			
</Rule>

The idea behind the SLD is to store the style information in the GML and reference it from the SLD. This works pretty well for a lot of other CSS parameters but not for this one.

When parsing this SLD with SLDParser.readXML() the following NPE is thrown:

java.lang.NullPointerException
	at java.util.StringTokenizer.<init>(StringTokenizer.java:182)
	at java.util.StringTokenizer.<init>(StringTokenizer.java:204)
	at org.geotools.styling.SLDParser.parseStroke(SLDParser.java:1879)
	at org.geotools.styling.SLDParser.parseLineSymbolizer(SLDParser.java:958)
	at org.geotools.styling.SLDParser.parseRule(SLDParser.java:888)
	at org.geotools.styling.SLDParser.parseFeatureTypeStyle(SLDParser.java:800)
	at org.geotools.styling.SLDParser.parseStyle(SLDParser.java:746)
	at org.geotools.styling.SLDParser.readDOM(SLDParser.java:319)
	at org.geotools.styling.SLDParser.readXML(SLDParser.java:295)

I observed this bug using GeoTools 2.5.7 and have not checked 2.6 yet (sorry).
