Dear Luis Bernardo,
 
I have to check if I share the Factory between threads - might be possible.
Thanks for running the single thread test.
In the meantime I have created a small test example - which should repoduce the 
problem - but it runs without producing the exception. So I will have a much 
deeper look at the problem and come back when I find out more.

Are you sharing the FopFactory between threads?

I ran an intense single threaded test that reuses the FopFactory and had
no problem. If you are running single thread then send your PDF so that
we can investigate.

 I have some additional information to the NullPointerException:

 - the result of pddoc.getDocument() (line 117) is Null
 - the Exception only occurs when reusing the FopFactory - never during the 
 first run.

 Maybe a problem with reusing the PDFBox? I will try to have a deeper look.

 Dear Luis Bernadro,

 I have now created a complete trunk version (fop, fop-pdf-image with pdfbox

 fop-pdf-images was updated with pdfbox-1.8.4 jars.

 if you checkout and run ant dist you get all the jars in an archive.

 I tried to apply the patches to the pdfbox trunk - where they failed and I 
 had some problems with figuring out the reasons (like a missing test class - 
 which is simple, and other moved code).
 But you are right, because 1.8.4 is a bugfix release they should work there 
 - so I should checkout the 1.8.4 branch instead of the trunk ;-)

 PDFBox-1.8.4 was only released a few days ago and that explains why
 fop-pdf-images is still using 1.8.3. I will update it today.

 Meanwhile, if you want to apply the two patches that fontbox needs, they
 are in the lib directory of the fop project. They were created against
 PDFBox-1.8.3, and possibly they can be applied cleanly to 1.8.4.

 Hello,

 my experience with the official trunk version is that PDFBox-1.8.3 has a 
 bug that is fixed in 1.8.4 that makes it impossible to use the 
 fop-pdf-image trunk at the moment - so would be nice if this could be 
 updated. I have not understand the pdfbox patches yet, so I was not able to 
 apply them to pdfbox 1.8.4.

 As you mention the official binaries are no longer usable for me, because 
 the pdfbox version included is to much outdated - and I need pdfbox too in 
 my code.
 At the moment I am thinking about using a separate class loader for the 
 official binaries, but in my eyes

Dear Simon Steiner,

thats no problem - as state one mail earlier the problem seems to be in context 
of reusing the FopFactory.

Hi,

You could check if the pdf can be read with adobe reader and pdf box

Using

java -jar pdfbox-app-x.y.z.jar PDFToImage PDF file

http://pdfbox.apache.org/commandline/#pdfToImage

Thanks

 Best way for me would be if fop-pdf-images-trunk could be updated to

 it is only broken software for me :(

 If you are using FOP-1.1 then you should use fop-pdf-images that you can get 
 from 
 https://dist.apache.org/repos/dist/dev/xmlgraphics/binaries/[https://dist.apache.org/repos/dist/dev/xmlgraphics/binaries/].
  That includes the PDFBox jars, but they are
