Configuration: Cocoon 2.0.3, Tomcat 3.2.3.
We use the SVGSerializer with JPEG-Output to generate graphical menus (we could not
get the customer to use only plain text menus).
All works fine after a starting up tomcat. But after a few days (variing) without even
touching the server the SVG Generantion fails with the Error below - a
ClassCastException. Every following request of a JPEG generation failes with the same
error.
All other requests processing only HTML still work!
This error is very strange, because all works until the SVG Serialization seems to
hang up totally (but only the SVG Serialization).
The memory utilisation is normal. There are no OutOfMemory-Erros or anything that
points to a memory leak. Unfortunately it was not possible to reproduce this problem
by force using a web stress tool, it only happens on the live servers and only after a
few days.
After a tomcat restart all works well again.
Any ideas? I searched the mailing lists of Cocoon and Batik but found hints.
We tried replacing the batik 1.5beta2 shipped with Cocoon 2.0.3 with the latest 1.5
beta3, same problem.
