             Summary: Update slf4j-api to 1.7.5
                 Key: WFLY-2437
                 URL: https://issues.jboss.org/browse/WFLY-2437
             Project: WildFly
          Issue Type: Component  Upgrade
      Security Level: Public (Everyone can see)
          Components: Logging
    Affects Versions: 8.0.0.Beta1
            Reporter: Jorge Solorzano
            Assignee: James Perkins


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.
