Steve McDowell commented on WFLY-2437:
--------------------------------------

I replaced just the jcl-over-slf4j jar with the latest version (1.7.7) and everything seems to be working still  and the thread contention problem is no longer evident.   Thanks.  :)

> The logger factories in most SLF4J modules namely in jcl-over-slf4j, log4j-over-slf4j, slf4j-jcl, slf4j-jdk14, slf4j-log4j12, and slf4j-simple now use a ConcurrentHashMap instead of a regular HashMap to cache logger instances. This change significantly improves logger retrieval times at the cost of some memory overhead.
> Acording to SLF4J developers:
> Given the significance of these performance improvements, users are highly encouraged to migrate to SLF4J version 1.7.5 or later.
