Lost spaces in my created pdfs (pdfbox & itextpdf)

Question

I'm using pdfbox & itextpdf to create very simple invoices in pdf format.

We're creating raw invoice text files in an erp system outside of java - so the only thing i have to do combining the textfile with a (pdf) template. (Thats not the problem. ;) )

It's working fine - but I found now an indentation error in the pdf: After the header of the table, the indentation goes wrong (one leading whitespace is removed).

What I'm doing wrong?

Thats the code, producing the sample pdf:

final File outputFile = this.createTmpFile();
final Document document = new Document(PageSize.A4);
PdfWriter.getInstance(document, new FileOutputStream(outputFile));
document.open();
final StringBuffer testText = new StringBuffer();
testText.append("                                                                 21.12.2012\n");
testText.append("\n");
testText.append("\n");
testText.append("\n");
testText.append("Invoice\n");
testText.append("\n");
testText.append("\n");
testText.append("Amount  Description                                         CUR       Price\n");
testText.append("===========================================================================\n");
testText.append("\n");
testText.append(" 1      Order #E41141454 from 01.01.2012:                   EUR       21,21\n");
testText.append("        nice text, nice text, nice text, nice text,\n");
testText.append("        nice text, nice text, nice text, nice text,\n");
testText.append("\n");
testText.append("        Status: online\n");
final Paragraph para = new Paragraph();
para.setFont(new Font(FontFamily.COURIER, 8.6f));
para.setAlignment(Element.ALIGN_UNDEFINED);
para.setLeading(1.2f, 1.2f);
final String t = testText.toString();
para.add(t);
document.add(para);
document.close();
