Re: Fop trunk / fop-pdf-images / PDFBox 1.8.4 -additional infos
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.
Greetings

Dear Luis Bernadro,
I have now created a complete trunk version (fop, fop-pdf-image with pdfbox 1.8.4 (patched), xmlgraphics trunk, batik trunk).
Now I end up with the following stack trace:

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.

Aw: Re: Fop trunk / fop-pdf-images / PDFBox 1.8.4 -additional infos
Posted by Kai Hofmann <po...@web.de>.
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.
Greetings

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.

Re: Fop trunk / fop-pdf-images / PDFBox 1.8.4 -additional infos
Posted by Luis Bernardo <lm...@gmail.com>.
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.
