The soffice --accept command-line option and the UNO 
css.bridge.UnoUrlResolver service expect different kinds of arguments. 
The latter is documented to expect a full uno URL (see 
<http://udk.openoffice.org/common/man/spec/uno-url.html>), while the 
former takes only connection-type,params and optional (defaulting to 
"urp") protocol-name,params parts of such a URL.  (Though the former was 
mis-documented to also take a uno URL, see 
<https://gerrit.libreoffice.org/#/c/72859/> "Fix documented 'soffice 
--accept' parameter syntax") for fixing that.

So run `soffice --accept=socket,host=localhost,port=2083\;urp` but call 
xResolver->resolve("uno:socket,host=localhost,port=2083;urp;StarOffice.ServiceManager").
