How to get Apache FOP to embed Fonts in a PDF/A-2b

Question

I'm using Apache FOP v2.6 & trying to generate a PDF/A-2b with one of the Base-14 Fonts Embedded.

I'm getting an org.apache.fop.pdf.PDFConformanceException:

"For PDF/A-2b, all fonts, even the base 14 fonts, have to be embedded! Offending font: /Helvetica"

Here's what I think is the relevant snippet of Code:

Any ideas what might be missing?

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.IOException;

import javax.xml.transform.TransformerException;

import org.apache.fop.Version;
import org.apache.fop.apps.FOPException;
import org.apache.fop.apps.FopFactory;
import org.apache.fop.apps.FopFactoryBuilder;
import org.apache.fop.configuration.ConfigurationException;
import org.apache.fop.configuration.DefaultConfigurationBuilder;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class PdfBuilder {

    private static final Logger     LOG = LoggerFactory.getLogger(PdfBuilder.class);

    private static final FopFactory FOP_FACTORY;
    /**/    static {
        final var fopConfigXml =
            """
                
                    
                        
                            
                                
                            
                        
                    
                
            """;

        final     var fopFactoryBuilder = new FopFactoryBuilder(new File(".").toURI());
        try {
            final var fopConfigStream   = new ByteArrayInputStream(fopConfigXml.getBytes());
            final var fopConfig         = new DefaultConfigurationBuilder().build(fopConfigStream);

            fopFactoryBuilder.setConfiguration(fopConfig);

            LOG.info ("FOP Config.:"       + " fopVersion={} xml.:{}{}", Version.getVersion(), "

        }
        catch (final ConfigurationException e) {
            LOG.error("FOP Config Error.:" + " fopVersion={} xml.:{}{}", Version.getVersion(), "
", fopConfigXml, e);
        }
        FOP_FACTORY = fopFactoryBuilder.build();
    }

    public byte[] generatePDFfromFO(final byte[] bytesFO) throws IOException, FOPException, TransformerException {

        final var foUserAgent = FOP_FACTORY.newFOUserAgent();
        /**/      foUserAgent.getRendererOptions().put("pdf-a-mode", "PDF/A-2b");
        :
        :
        :
        :
        return pdfBytes;
    }
}
