Java registering a provider throws EOFException

I am using iText to convert html to pdf and when I try to register a fontProvider I get EOFException, here is the relevant code:

XMLWorkerFontProvider fontProvider =new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("resources/fonts/NotoSansHebrew-Regular.ttf"); //this row throws the error

I had placed NotoSansHebrew-Regular.ttf under resources, like iText-rtl.

Here is the full code:

public void createPdf(String file, String htmlString) throws IOException, DocumentException {
        // step 1
        Document document = new Document();
        // step 2
        PdfWriter writer =
            PdfWriter.getInstance(document, new FileOutputStream(file));
        // step 3
        document.open();
        // step 4
        // Styles
        CSSResolver cssResolver = new StyleAttrCSSResolver();
        XMLWorkerFontProvider fontProvider =
            new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
        fontProvider.register("resources/fonts/NotoSansHebrew-Regular.ttf");
        CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
        HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
        htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());

        // Pipelines
        PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
        HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
        CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

        // XML Worker
        XMLWorker worker = new XMLWorker(css, true);
        XMLParser p = new XMLParser(worker);
        p.parse(new FileInputStream(htmlString), Charset.forName("UTF-8"));
        // step 5
        document.close();
    }

main:

public static void main(String[] args) throws IOException, DocumentException {
    Converter test = new Converter();
    test.createPdf("C://Users//t207322//Desktop//digitalCheck//test.pdf", "C://Users//t207322//Desktop//digitalCheck//test.html");
}

And the stack:

Looks like the path to your font "resources/fonts/NotoSansHebrew-Regular.ttf is invalid. Try to use absolute path.
