I take back what I said. It seems there are classpath resolution issues when using a custom "JettyLauncher" while running under "GWT Eclipse Plugin", probably due to different classloaders assignment.
I am afraid the time has finally come to abandon use of DevMode and the "GWt Eclipse Plugin", until this is fixed in later versions of GWT. I hope a future version of GWT will make use of a Jetty version supporting a more elegant way to override the "allowedFromSystemClassLoader" variable.
