Tilman,
I ran the code on the OPs behalf and can confirm that this issue still
exists without PDFBOX. I changed the Font size to 144 and the numPages to
4.
These are my test results:
- PASS: All pages
- PASS: First page only (1-1)
- PASS: First three pages (1-3)
- *FAIL: Second page only (2-2)*
Nothing printed
- *FAIL: Last page only (4-4)*
Nothing printed
- *Fail: Last two pages (3-4)*
Nothing printed
- *FAIL: Last three pages (2-4)*
This one's interesting because it DOES print but only pages 3-4.
This smells like an off-by-one error. I opened a ticket with my company's
OpenJDK support team. The assigned dev is on vacation so there's no
upstream bug report to link yet.
Thanks for the code snippet, I'll provide this with the private bug report
as it'll greatly help narrow down the cause.
