[slf4j-user] Use same message in log and Exception

[Jacob Kjome]

Maybe you have a unique situation, but the general rule is that you log where you
handle the exception, not where you throw it.  Otherwise you may end up with logs
containing duplicate messages.

Personally, I'd just do...

throw new SomeException(String.format("Asdf asdf asdf qwer=%s asdf zxcv=%s", obj1,
obj2));

Then log the exception where you handle it.
