Claus Ibsen commented on CAMEL-3759:
------------------------------------
You can only use at most 2 placeholders like that. If you need 3 or more, you
have to do it the old fashion way.
Unfortunately sfl4j doesn't support varargs.
> After switching to slf4j, we can get rid of the 'isTraceEnabled',
> 'isDebugEnabled' and 'isInfoEnabled' statements
