Issue

• We were getting java.io.IOException: Stream closed after logging the message using <log> spring dsl method
  Description. It should smoothly convert the StringReader message to String , and should have close the stream. Sample route:-

<route>
    <from uri="switchyard://HttpService" />
    <recipientList>
        <method bean="ResolutionBean" method="someEndpoint"></method>
    </recipientList>
    <log message="Print body ${body}"/> 
</route>
