------------------------------------

 Would this create a runtime conflict (haven't checked myself to see if 1.7.5 
is fully backward compatible with 1.4.3 & later) ? Can you please confirm if 
this doesn't break anything particularly retention, replication, recordsize and 
post-processing actions? If there are no conflicts, this would be a good change.

> SLF4J 1.7.5 provides interesting performance improvements.
> More over, it's not more require to test the log level, we can use directly
