title: Why do I get "NoSuchMethodException" & "IOException upon attempt to marshall", error?
body: <p>I am seeing a very large number of the errors below in my log files. Nothing <em>seems</em> to be causing them in the way that none of our users are seeing any errors. What could be causing them? We are running CF 8.</p>
  
  <p>FYI: They are happening many times per second.</p>
