> These INFO messages are causing me issues. I'm calling PDFBox to Extract
text from a PDF file, within a PHP script. The extracted text is output to
the 'console' which I then read in PHP as the 'stdout' from the program.
Errors I read from a similarly piped 'stderr'.

programs in PHP is very flaky and so I cannot use an exit code of 0 from
PDFBox to determine success or failure.  The only way I can check whether
everything was ok is to check the contents of stderr.

though everything is ok (I understand it is safe to ignore these particular
INFO messages). I am forced to having to parse the stderr and use a regex
to delete these info messages and see if there is then anything left which
might mean error. This is not very good practice :(

stderr? I have tried searching and found some stuff on log4j which I tried
to make sense of, but I've no idea if I'm on the right track, or even how
to use it!

display.  The "Proposed Insured" pdf fields (pdf field name:
InsuredFullName) at the top of page 3 & 4 displays correctly, but the same
field at the top of page 5 does not.  I do see the expected image if I use
Adobe Reader which is why I am turning to you.  I display the image on a
JPanel using the PDPage.convertToImage() method, but PDFToImage displays
the same output. I have attached the pdf.  I am happy to attach images
separately; they won't fit under 1MB.  I wish I knew more about the PDF
specification, so I could describe what is wrong.
