PDFBox EOFException: null when setting textfield value

I am trying to fill in a pdf form created with adobe acrobat, the form contains one text field named 'txt_name'. To fill in the form I am using Apache PDFBox.

Code to fill pdf form

        try {
            PDDocument pDDocument = 
            Loader.loadPDF(ResourceUtils.getFile("classpath:pdf/test.pdf"));
            PDAcroForm pDAcroForm = pDDocument.getDocumentCatalog().getAcroForm();
            pDAcroForm.getField("txt_name").setValue("test");
            pDDocument.save("./src/main/resources/pdf/generated/test.pdf");
            pDDocument.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

As you can see I am loading in the pdf file named 'test.pdf'. After this I want to fill in the field with the name 'txt_name' and set the value to 'test', however when I try to fill in the field I get an EOFException. I also get the error 'Could not load font file: C:\WINDOWS\FONTS\mstmc.ttf'. I do not have this file on my computer but when I try to find anything online about this I don't get any good results.

PDFBox version:

        <dependency>
            <groupId>org.apache.pdfbox</groupId>
            <artifactId>pdfbox</artifactId>
            <version>3.0.0-RC1</version>
        </dependency>

I also tried different version but this would not work.

Deleting the mstmc.ttf file worked for me, the file is not a font. PDFbox is trying to read this file but since it is not a font it is not able to read the file, this is what causes the error.

Thanks to @mkl and @Tilman hausherr who helped me out.
