An update for those interested: struts.properties defines "struts.dispatcher.parametersWorkaround" (false by default), and says it's for some app servers that don't handle HttpServletRequest.getParameterMap() (including mine, OC4J):
http://struts.apache.org/2.x/docs/strutsproperties.html This sounds very closely related, but changing it to true didn't solve the problem. I made sure the relevant boolean flag got set and affected behavior in org.apache.struts2.Dispatcher, where the prepare(HttpServletRequest, HttpServletResponse) method executes request.getParameter("foo") if paramsWorkaroundEnabled is set. The comment: 'simply read any parameter (existing or not) to "prime" the request'. My guess is that this forces the request to process the ServletInputStream and build the parameter map; not sure, though. No (URL) parameters have yet appeared. Looking at the byte[] in the ServletInputStream, it's easy to find the original URL with all parameters intact, but the offset (several hundred) seems to indicate that something has already processed it.
