Please try the following code using iText 7 java.

         ByteArrayOutputStream baos = new ByteArrayOutputStream();
         PdfDocument pdfDocument = new PdfDocument(new PdfWriter(baos ));
        Document doc1 = new Document(pdfDoc).add(new Paragraph("Hello there..."));
        doc1.close();
        baos.close();
        byte[] bytes = baos .toByteArray();
