wadl2java : Return types aren't generated properly on server interfaces for methods with more than 1 response element.

My wadl file frequently has more than 1 response element in the method elements, i.e.:

<method name="GET" id="getUserDefaults">
	<doc>Gets default user configuration values.</doc>
	<response status="200">
		<representation mediaType="application/xml" element="fmc:userDefaults" />
	</response>
	<response status="400">
		<representation mediaType="application/xml" element="fmc:errorList" />
	</response>
</method>

If there is more than 1 response element, the wadl2java tool assumes that the return type from generated methods is always void. There is a line of code that checks for exactly 1 response element - if there isn't 1 (i.e. 0 or more than 1), then void is assumed. Can it not take the representation of the 1st response in a case when there is more than 1 (or better, the representation from the response with a success status)?
