rule based sld error while publishing geopacakge

Description

Hi all,

When publishing a layer from geopackage, and the SLD contains a rule, then it may raise an exception while rendering. This happens randomly. I've found this behaviour with line and polygon layers so far.

The same sld works perfectly when publishing the equivalent table from other datasources, such as sql server.

Sample rule:

<ogcropertyIsEqualTo>
<ogcropertyName>DESCRIPTIO</ogcropertyName>
<ogc:Literal>UNDIFFERENTIATED FAULT</ogc:Literal>
</ogcropertyIsEqualTo>

Exception raised:

2018-05-24 16:19:42,773 TRACE [org.geotools.util] - Error applying the converter class org.geotools.util.GeometryConverterFactory$1 on (UNDIFFERENTIATED FAULT,class com.vividsolutions.jts.geom.MultiLineString)

Looking at the code:

private Geometry readGeometryTaggedText() throws IOException, ParseException {
String type = null;

try{
type = getNextWord();
}catch(IOException e){
return null;
}catch(ParseException e){
return null;
}

if (type.equalsIgnoreCase("POINT")) {
return readPointText();
}
else if (type.equalsIgnoreCase("LINESTRING")) {
return readLineStringText();
}
else if (type.equalsIgnoreCase("LINEARRING")) {
return readLinearRingText();
}
else if (type.equalsIgnoreCase("POLYGON")) {
return readPolygonText();
}
else if (type.equalsIgnoreCase("MULTIPOINT")) {
return readMultiPointText();
}
else if (type.equalsIgnoreCase("MULTILINESTRING")) {
return readMultiLineStringText();
}
else if (type.equalsIgnoreCase("MULTIPOLYGON")) {
return readMultiPolygonText();
}
else if (type.equalsIgnoreCase("GEOMETRYCOLLECTION")) {
return readGeometryCollectionText();
}
throw new ParseException("Unknown geometry type: " + type);
}

In conclusion, it seems that somehow the function is being given the data value related to the rule instead the geometry type. Please note the coincidence "Unknown geometry type: UNDIFFERENTIATED" and the literal in the rule.
