I had to exclude this dependency: org.slf4j</gro

I had to exclude this dependency:

org.slf4j slf4j-simple

Otherwise my application using Spring Boot complains about two SLF4J implementation.

Thanks for reporting this issue. It has been (hopefully) fixed in 0.9.1, the SLF4J dependency is now only for the demo app. Please let me know if there are still problems with that dependency.

That was fast! Thank you very much.
