All I can say is that it's much better (for several reasons) to just write

MSG_ERROR("This is a test error message.");

and you should never need to explicitly call
getLog("my.log.hierarchy")... Analysis::getLog() will put the name in
automatically.

I don't know anything about how Herwig++ is interfacing Rivet... David,
can you help?
