This does seem to be a downside of embedding the SLF4J api into
JSecurity: you would still need one of the binding JARs. Because it
uses static binding, you can't simply provide a default implementation
and then override it with another.

That said, SLF4J uses static binding partly to avoid class loader
issues, so I'm slightly worried that a JSecurity logging facade may
end up with similar problems to Commons Logging. Saying "it's really
simple" and "it's already done" always gives me second thoughts - I've
seen way too many problems with code that was supposed to be really
simple :)

At the risk of confusing users with the number of different JSecurity
JAR files they can use, how about a jsecurity-nodeps.jar that
basically incorporates slf4j-api.jar and slf4j-jdk14.jar? I'm not sure
it's worth it, but it's an option.

Cheers,

Peter
