JRXML unable to load

However I try to load my JRXML, I keep getting this error:

    net.sf.jasperreports.engine.JRException: org.xml.sax.SAXException: http://java.sun.com/xml/jaxp/properties/schemaSource

Here is my code:

    public class DownloadService {
        public static final String TEMPLATE = "C:/reports/report.jrxml";
        protected static Logger logger = Logger.getLogger("service");
    
        Connection conn;
    
        public void download(String type, HashMap params, HttpServletResponse response) throws FileNotFoundException {
            try {
                //conn =jspDAO.getSqlSession().getConnection();
    
                try {
                    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
                    conn = DriverManager.getConnection(
                            "jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1521:test", "test",
                            "test"); //censored
                    System.out.println("Getting connection.....");
                    System.out.println(conn);
                } catch (Exception e) {
                    e.printStackTrace();
                }
    
    
                InputStream reportStream = new FileInputStream(TEMPLATE);
                System.out.println("Retrieved template");
                // 3. Convert template to JasperDesign
                System.out.println("Loading jrxml");
                System.out.println(reportStream.toString());
                JasperDesign jd = JRXmlLoader.load(reportStream);
                System.out.println("Loaded jrxml");
                // 4. Compile design to JasperReport
                System.out.println("Compiling JasperReport");
                JasperReport jr = JasperCompileManager.compileReport(jd);
                System.out.println("Compiled JasperReport");
                // 5. Create the JasperPrint object
                // Make sure to pass the JasperReport, report parameters, and data source
                System.out.println("Creating JasperReport");
                JasperPrint jp = JasperFillManager.fillReport(jr, params, conn);
                System.out.println("Created JasperReport");
                // 7. Export report
                System.out.println("Exporting report");
                JasperExportManager.exportReportToPdfFile(jp, "C:/reports/pdfOutput.pdf");
            } catch (JRException jre) {
                logger.error("Unable to process download");
                logger.error(jre);
                throw new RuntimeException(jre);
            }
        }
    }

I am unable to get past JasperDesign jd = JRXmlLoader.load(reportStream);

Here is what my logger outputs:

Is there anything that I could try to solve this?

EDIT

I am unable to post my XML, but it was created with iReports 3.1.3. I am using JasperReport 3.5.3 due to compatibility issues with the latest versions.
