poll: which logging framework are you using

[Maarten Bosteels]

It would be interesting to know which logging framework your MINA
applications are using.

[ ] log4j
[ ] logback
[ ] java.util.logging
[ ] slf4j-simple
[ ] slf4j-nop
[ ] x4juli
[ ] other (please specify)

Please, check all that apply.

Thanks,
Maarten
