you should really upgrade either to the latest 1.8 release or to 2.0 release (the 1.8 API is more in line with 1.6 where 2.0 saw several changes - development now mainly goes into 2.0). In both there were many additions when it comes to parsing malformed PDFs. In addition - with the tremendous help of the TIKA colleagues - text extraction is now run against a much larger test corpus. You can download the pdfbox-app…jar http://www-us.apache.org/dist/pdfbox/2.0.6/pdfbox-app-2.0.6.jar http://www-us.apache.org/dist/pdfbox/1.8.13/pdfbox-app-1.8.13.jar and run the ExtractText command line tool to verify if the issue you are facing is still relevant with the newer versions. 1.6.0 has been release in Juyl 2011 - so yes, quite old.
