Remko Popma resolved LOG4J2-1225.
---------------------------------
Resolution: Won't Fix
Assignee: Remko Popma
I remember now why I did it this way: the Logger API has two separate methods:
{code}
void debug(Supplier<?> objectMessageSupplier);
void debug(MessageSupplier messageMessageSupplier);
{code}
{{Supplier<?>}} is a lambda that returns some object, which the API will wrap
in a Message object by calling {{messageFactory.newMessage(supplier.get())}}.
{{MessageSupplier.get()}} on the other hand returns a {{Message}} object, so no
need to invoke the message factory.
It would be confusing if MessageSupplier would extend the Supplier interface,
and in fact, I think the wrong overloaded method was called when I tried this.
So this is by design.
> MessageSupplier should extend Supplier<? extends Message>
