Bad character in IRI in Jena when reading OWL/RDF model

I have a org.apache.jena.riot.RiotException: Bad character in IRI (space) exception when reading an OWL/RDL model in Jena.

I know that it's because I have a space in an IRI declaration in an XML namespace declaration (which is not allowed), but as I am using Jena in an open Source tool I developed to create the graph corresponding to an ontology, I would like to know the number of the line in the (XML) model where the error occur. Is it possible in Jena when catching this exception?

You can supply an error handler using

RDFParser.source("filename").errorHandler(...).toModel();

It will actually be warning from the parser (the error is generated later when the line number isn't available)

To change it to an error:

  Map<String, Object> properties = new HashMap<>();
  properties.put("WARN_BAD_NAMESPACE_URI", "EM_ERROR");
  Context cxt = new Context().set(SysRIOT.sysRdfReaderProperties, properties);
  RDFParser.source(filename)
           .context(cxt)
           .errorHandler(....)
           .toModel();
