Subject Aw: Re: Fop trunk / fop-pdf-images / PDFBox 1.8.4 -additional infos
Date Mon, 10 Feb 2014 10:44:39 GMT
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.

Note that FOP-trunk includes a patched fontbox-1.8.3 (and you should use it instead of the
official fontbox-1.8.3). It is expected that FOP will use the official fontbox jar in the
near future.
