Global styling preference doesn't work?

Hello There 

I am using jasper reports library 6.17.0 to make nice dfp files wich is lovely)

After lates update I have faced with rectangle border issue - the border became visible (the border was here always but was invisible because overlaping).

<detail>
 <band height="20" splitType="Prevent">
  <rectangle>
   <reportElement style="alternateRow" stretchType="RelativeToBandHeight" x="0" y="0" width="539" height="20"/>
  </rectangle>
  <textField isBlankWhenNull="true" pattern="d MMM yyyy">
...........
  </textField>
.................
 </band>
</detail>

pens still overlaped partyally but visible. Note that my 'alternateRow' styling is not a reason, it do not draw any pens, just overlap the rectabgle's ones.

I really want to make it invisible. I can do it easely for certain report like:

<rectangle>
 <reportElement style="alternateRow" stretchType="RelativeToBandHeight" x="0" y="0" width="539" height="20"/>
 <graphicElement >
  <pen lineWidth="0.0"/>
 </graphicElement>
</rectangle>

but I need to do it globally since I have a lot of smulat templates. As I understood the :

net.sf.jasperreports.style.pen.lineWidth=0.0

property is exactly what i need (docs: http://jasperreports.sourceforge.net/config.reference.html#net.sf.jasper...) but can not set it globally.

I have tried to put it into jasperreports.properties file - no luck (note that other jasper props from thatfile applies correctly)

I have tried to set it programmatically in java code like:

var exporter = new JRPdfExporter();
exporter.setExporterInput(SimpleExporterInput.getInstance(printJobs));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(exportOutput));
 
SimplePdfExporterConfiguration conf = new SimplePdfExporterConfiguration();
conf.setCompressed(true);
exporter.setConfiguration(conf);
exporter.getExporterContext().setValue(net.sf.jasperreports.engine.style.PropertyStyleProvider.STYLE_PROPERTY_PEN_LINE_WIDTH, "0.0");
exporter.getExporterContext().getJasperReportsContext().setProperty(net.sf.jasperreports.engine.style.PropertyStyleProvider.STYLE_PROPERTY_PEN_LINE_WIDTH, "0.0" );

No affect!

Eventyally I have put it into JRXML file directly:

<property name="net.sf.jasperreports.style.pen.lineWidth" value="0.0"/>
Doesn't help.
 
Dear support, could you please let me know what I am doing wrong?
Thanks
