Hello,
I am facing a strange issue with our product, which was recently ported to
cocoon 2.2 and is now in the final stabilization phase. It seems that for
some reason various exceptions occure on the log which might have
something to do with servlet service framework or inproper configuration
of jetty. this particular exception is repoduceable as we get it, when
driving a seleninium testcase against an embedded jetty/hsqldb
configuration of our product.
Interestingly this does not have any bad consequence in the frontend.
however something seems to go wrong...
Stacktrace:
