{noformat}
Here is an excerpt of the SLD causing this (I can provide a full version if
necessary):
{noformat}
<sld:Rule>
<ogc:Filter>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>water_type</ogc:PropertyName>
<ogc:Literal>UE_NOOSA</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:Filter>
<sld:LineSymbolizer>
<sld:Stroke>
<sld:CssParameter name="stroke">
<ogc:Literal>#000044</ogc:Literal>
</sld:CssParameter>
<sld:CssParameter name="stroke-width">
<ogc:Literal>3</ogc:Literal>
</sld:CssParameter>
<sld:CssParameter name="stroke-offset">
<ogc:Literal>0</ogc:Literal>
</sld:CssParameter>
<sld:CssParameter name="stroke-dasharray">
<ogc:Literal>2.0 1.0 4.0 1.0</ogc:Literal>
</sld:CssParameter>
</sld:Stroke>
</sld:LineSymbolizer>
</sld:Rule>
{noformat}
The exception seems to be triggered by the presence of the stroke-dasharray CSS
parameter, if I remove that everything render fine (but not dashed).
