I noticed this same error when attempting to use the Run Jetty Run eclipse plugin with Jetty 6.1.26. Changing it to use Jetty 7.5.1 fixed the problem. We still use version 6 on our test servers without a problem though so I just put it down to some classpath issue with the plug-in.

I am running some drools application code through Jetty and I get the
following error.  I'm guessing its something to do with a conflicting jar or
dependency?  Any help would be much appreciated.  It does not happen when I
run it through tomcat 7.
