well, maybe you can just override the VVS's getResponseWriter() method
somehow to try calling/using getOutputStream() on requests first. but
i'm not sure that will do the trick. it might, if it's just
StringWriter that is the problem and the whole of the tile's content
can be reasonably held in memory with a ByteArrayOutputStream (which
is what the ImportResponseWrapper uses to hold the tile content if
getOutputStream() is called instead of getWriter()).
might be worth a shot at least.
