error when using svg2png serializer
I keep getting this error from cocoon, whenever I use the svg2png
serializer. I checked the archives for this, and found a few people with
similar errors, but it seems none of them had a reply. The error only
appears in the logs, and does not seem to cause any problems, but it is
a little worrisome, as I would like it to not generate any errors at
all.
Here is the error:
ERROR (2002-09-25) 16:46.34:030 [access] (Unknown-URI)
Unknown-thread/CocoonServlet: Cocoon servlet threw an Exception while

It seems the serializer closes the output stream. I'm not
sure whether this happens in the Cocoon serializer component
or in tha Batik raster processor. Search the serializer source
for "close()", if there is none, rise a question on batik-user,
perhaps someone over there knows. Sifting through the Batik
source is only for beings more persistent than me...

Yes, I have noticed this also, but the problem is the XML, the SVG is
being made from is dynamic, so the png is being remade quite often.

I've seen this too. It seems to happen the first time each of my
svg's are accessed. Once they are cached (in Cocoon) further
accesses don't cause the error.
I'm using Tomcat 4.0.4, Cocoon 2.0.4-dev, JDK 1.3
