Hi
Sorry, I guess in the strictest sense this is xmlgraphics-common
related now, but it was discovered and investigated using FOP 0.95beta.
We upgraded from 0.94 to use the new bookmarks features and our
software became globally unstable, hanging randomly during PDF
generation -- to be precise, getting all kinds of random problems
during image loading.
The images we use are stored in SVN and retrieved via their HTTP URLs
from an SVN server. Reading the SVN logs, we see a very different
behaviour between 0.94 (which worked fine and has been retested
since) and 0.95beta: the FOP requests litteraly "suffocate" the SVN
server, sending quite a lot of requests for images and taking way too
long to consume the responses. So, after a (random) while, the SVN
server gives up (timeout) and the FOP application on the other side
crashes immediately after. At least that is how we understand the
problem after testing and reading all sorts of server logs (with a
sysadmin) for a whole day.
This looks like a major regression and makes 0.95beta completely
unusable for us -- though we badly need the new features :-(
If anybody had an idea, I must say I'd be extremely grateful...
Two questions, for the moment:
Which image format(s) are you using?
PNG only (but lots of them).
Does the JAI/ImageIO implementation on the box where FOP runs, have a
native codec to read that format?
Will ask / investigate (it's a production server to which I don't have
direct access). Debian 4.0 on JDK 1.5.0_11 and JBoss 4.2.1.GA.
Thanks !
