[SOLVED] stomp content-type header set to plain for xml content

I'm sending a XML content to ActiveMQ from ruby script using stomp

I'm explicitly setting the content-type header toapplication/xml;charset=utf-8 as shown below

client.publish queue, xml, {'content-type'=>'application/xml;charset=utf-8'}

But when I read the message from a java client that uses spring-integration to read the message the content-type is text/plain.

As a result when unmarshaller is invoked the parsing is failed with the exception

1448446 [org.springframework.jms.listener.DefaultMessageListenerContainer#0-1] WARN org.springframework.jms.listener.DefaultMessageListenerContainer - Execution of JMS message listener failed
