----------------------------------------
@patrick
there is no such for thing for slf4j. slf4j is just the logger interface, the
api.
you can configure the final logger by jmx, like log4j, sure. but which logger
you use, this you can only know in your end project. as long as you are not
"there", you can not configure anything. it makes no sense, since you just do
logging in your code. thats why ManagedUtil could go to contrib, its log4j
specific jmx stuff.
in "tests" you will also chose a final logger, like log4j, "tests" are a final
project. but this dependency should only be visible in tests. zookeeper itself
should not deliver with log4j dependencies anymore.
is it possible in ANT scripts to have a special test scope with test specific
dependencies?

> Hello,
> i would like to see slf4j integrated into the zookeeper instead of relying
> explicitly on log4j.
> slf4j is an abstract logging framework. There are adapters from slf4j to many
> logger implementations, one of them is log4j.
> The decision which log engine to use i dont like to make so early.
> This would help me to embed zookeeper in my own applications (which use a
> different logger implemenation, but slf4j is the basis)
> What do you think?
> (as i can see, those slf4j request flood all other projects on apache as well
> :-)
> Maybe for 3.4 or 4.0?
> I can offer a patchset, i have experience in such an migration already. :-)
