ConcurrentModificationException under Jetty

I just upgraded various library dependencies in a project I'm working  
on, and am now getting the exception shown below on every request,  
but only when running under Jetty (via the Maven2 plugin). The same  
app runs fine under Tomcat. Is Shale doing anything in  
afterRenderResponse() that it shouldn't be, or is this likely a Jetty  
issue? Or am I barking up all the wrong trees? :-)
