There are no spaces in the PDF, that's why. Everything is drawn by position.
You get spaces in text extraction because they are added as a guess. See
attached image, which is the output of the DrawPrintTextPositions.java example.
PS: The current version is 2.0.5.

> Key: PDFBOX-3749
> URL: https://issues.apache.org/jira/browse/PDFBOX-3749
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.4
> Environment: Windows 10 64-bit
> Reporter: Harun Reşit Zafer
> Priority: Minor
> Labels: extraction, style
> Attachments: contract_00105_SEDAR-marked-1.png,
> contract_00105_SEDAR.pdf
>
>
> We overwrote the {{void writeString(String text, List<TextPosition>
> textPositions)}} method of the {{PDFTextStripper}} to extract additional
> position and style information from the PDFs. We thought this method would be
> called per line and the elements of the parameter {{List<TextPosition>
> textPositions}} would be all the letters, including the spaces in a line.
> This is indeed the case for thousands of the documents. However, one
> particular document, this is not the case and the {{textPositions}} contains
> just the letters of a word and {{writeString}} is called per word.
> I am not sure if this would be counted as a bug because the final extracted
> text is not affected.
> The problematic PDF is attached.
