Description

My goal here is to be able to say:

Logger log = LogManager.getLogger(Foo.class, new MyMessageFactory())

Where MyMessageFactory extends a MessageFactory:

and overrides:

public Message newMessage(String message, Object... params)

{ return new ParameterizedMessage(message, params); }

as:

public Message newMessage(String message, Object... params)

{ return new StringFormattedMessage(message, params); }

which would let me use native Java formatting instead of {} formatting /easily/

I've attach the idea as the beginning of patch, which is missing the LogManager bits.

Maybe we need a sub-interface of Message for param message, which would make me want to rename the class ParameterizedMessage to SimpleParameterizedMessage.
