{{importPage}} doesn't use template so output size is bigger (
[^output-importpage.pdf]).
Trying to import 2, 3, 2, 3 sequence, pdf is ok ( [^output-23.pdf])

> Project: PDFBox
> Issue Type: Bug

> I'm trying to create a pdf, starting from another on, using "template"
> techinque to optimize output size when pages is repeated. I will print text
> values with PDPageContentStream for each page. From the second import of
> first page, all written texts are duplicated also in page 1!
> In this sample I compose pdf with input page in sequence: 1, 2, 1 finally 2
> (view attached output.pdf). First and third output page have same texts
> ("page 1" and "page 3"!):
