> When switching to a new page using PDFDocumentGraphics2D#nextPage() the
> current content is added to the PDF document but it is not cleared. Therefore
> the same content will be repeated on the next page.
> nextPage() calls closePage() which adds this.getString() to the PDFStream.
> this.getString() simply returns the content of currentStream, a StringWriter.
> The content of currentStream is never cleared and the reference is never set
> to null. Therefore it will be appended to and it will be added again when the
> next nextPage() or closePage() or therefore finish() is called.
> A work-arround is to manually set the value of currentStream to null using
> reflection.
