RTMP in Coldfusion10 - Type 'coldfusion.flash.messaging.CFRTMPEndPoint' not found

I'm trying to use RTMP with Coldfusion 10 and the embedded livecycle ES.  The other channels and endpoints

have been working fine, but when the server starts up I get an error complaining that the endpoint cannot be

found for the cf-rtmp channel.   I'm using the standard setup with no special configuration.

The AMF channel, polling channel, etc. work just fine, and there are no complaints

about those channels or endpoints when the server starts up.

This is the error in the logs when the server starts up:

INFO: ColdFusionStartUpServlet: ColdFusion: VM version = 23.7-b01
