OK, I'll have a look at the problem and find a solution.

The problem is reproducible on jdk-7, not reproducible on jdk-8.
Fix for jdk-7:

runtime 'ch.qos.logback:logback-classic:1.1.2'

Thanks for looking into this. I was stuck for a few days until I finally managed to scope down the problem. Do you know what exactly this is all about? Adding logback sounds more like a work around. If someone would like to use some other logging implementation with SLF4J, this may not be an option.

That was a quick and dirty solution, yes. I'll look deeper into dependencies of your project to understand what's the root of the problem.

I'm actually getting this problem on JDK-8.. it was working perfectly until today and now the whole hell broke loose and it doesn't seem to be working for me anymore :(

Did you have a chance to dig into this more?

@alexejk, please open a new issue and post the complete log (if inconvenient to post it on github, send it over email).
