The dev-java/pdfbox ebuild currently has: HOMEPAGE="http://www.pdfbox.org" This takes you to a website about Jennifer Aniston’s Stripper-Body. I don't have anything against Jennifer Aniston, but the ebuild should use the correct homepage: HOMEPAGE="http://pdfbox.apache.org"
Hm, actually it seems that Portage does not ship Apache's PDFBox, but a old version instead, prior to it becoming an Apache project. And the website died and now serves spam. Changing the HOMEPAGE to point to the Apache version would be wrong, as it's not what the ebuild installs. In any event though, the HOPEPAGE has to be changed to something else.

Fixed. Thanks!
I used the apache homepage, because that is the future project and probably the best reference if someone is looking for help. I hope to see a bump for pdfbox soon.
