error handling async instead of sync

[Marco Westermann]

Hi,

I have a route with an errorHandler configured. I set it to redeliver 
async. But when an error occures the remaining messages on the queue are 
processed after the redelivery of the failed message ends.

Here is my routebuilder: http://pastebin.com/8fUED75R

Is there something wrong with it? I use camel 2.10.4

the process method which is invoked from the route logs a line: 
processing new order 123123
and my log looks like this: http://pastebin.com/iLE6MqJJ

why is my redelivery sync instead of async?

best regards,

Marco
