Problem with matrix params, works with one, but not with two (or more) params

Hello,

I'm having a problem where matrix parameters are not recognized past the
first parameter.  When I have one matrix parameter, the method below is
invoked and the PathSegment.getMatrixParameters() returns the single
result.

However, if I append a second matrix parameter (or more), the service
method is not invoked at all and I receive the following error message:

"No operation matching request".

Service interface:

@GET
@Path("/renderwidget/id/{widgetID}/type/{widgetType}/size/{size}/locale/{locale}/{properties}")
    WSWidget renderWidget(@PathParam("widgetID") Long widgetID,
            @PathParam("widgetType") Integer widgetType,
            @PathParam("size") Long containerSize,
            @PathParam("locale") String locale,
            @PathParam("properties") PathSegment props)
            throws RemoteBridgeException;

Working
URL: /renderwidget/id/1007/type/1/size/1/locale/en_US/properties;numResults=1

Broken:
URL: /renderwidget/id/1007/type/1/size/1/locale/en_US/properties;numResults=1;foo=bar

The reason I'm trying to use matrix parameters is that I have an
arbitrary map of name/value for a widget class.  I can't try to parse
them out individually using @MatrixParam, because they vary by widget
class and are not known at the service level.

Thanks for your help.
