BTW: Which of the providers are you using to see the problem? I'm 
wondering if you might have converted them to explicit modules rather 
than leave them as automatic modules.  FWIW, I don't see any issues when 
using the simple/default implementation:

$ java -p mlib --list-modules slf4j.api,slf4j.simple
automatic module slf4j.api at 1.7.25 (file:///d/mlib/slf4j-api-1.7.25.jar)
   requires mandated java.base
   contains org.slf4j
   contains org.slf4j.event
   contains org.slf4j.helpers
   contains org.slf4j.spi
automatic module slf4j.simple at 1.7.25 
   requires mandated java.base
   contains org.slf4j.impl

$ java -p mlib--add-modules slf4j.api,slf4j.simple -m m/p.Main
[main] INFO p.Main - started
