stack trace re: "org.mule.DefaultMuleMessage: setProperty(key, value) called

[CL Kim]

As requested in the mule-console.log, here is the warning and stack trace entry that we saw while fixing our integration tests.
(As an aside, we now don't have the need to set the "httpStatus" property, so this warning should go away for us very soon anyway, but just wanted to share the log entry, as requested in the message.)
