Problems getting ES 1.4.1 to start on Jetty 1.2.1

[rimpi05]

Hello,
We recently updated to ES 1.4.1 from ES 1.3.4 with the following setting:
"http.type" => "com.sonian.elasticsearch.http.jetty.JettyHttpServerTransport"

However, on testing some ES nodes start and some don't. Following is the stack trace thrown on failed nodes:

Any pointers to what may be going on here?
