http uri-variable escaping '?'

[dturanski]

Test Using the latest 2.2.0.BUILD-SNAPSHOT (also in RC2)

 <int-http:outbound-gateway url="{url}" request-channel="inputChannel" http-method="GET" expected-response-type="java.lang.String" 
   	reply-channel="outputChannel">
       <int-http:uri-variable name="url" expression="'http://www.google.com/finance/info?q='+ payload"/>
    </int-http:outbound-gateway>
    
    <int:channel id="outputChannel">
    	<int:queue/>
    </int:channel>

RestTemplate: GET request for "http://www.google.com/finance/info%3Fq=VMW" resulted in 404 (Not Found); invoking error handler.

This worked fine in 2.1.3.RELEASE (no escaping '?'). Fails with 2.1.4.RELEASE. Is this a bug? Is there a workaround?

Were you using Spring 3.0 with 2.1.3 and 3.1 with the others (including 2.1.4)??

I recall there was a change in Spring 3.1's RestTemplate, but I am having trouble locating the forum post(s).

The work-around (IIRC) is to use {firstPart}?{secondPart} with 2 <uri-variable/>s.
