please try using the setSortByPosition option
https://pdfbox.apache.org/docs/2.0.12/javadocs/org/apache/pdfbox/text/PDFTextStripper.html#setSortByPosition-boolean-
as this will return the text in "visual" order and not in the order the text
objects appear in the PDF. Dependent on the input
PDF this might give you a better result.
