             Summary: Static Logger Lookup is much slower as with JDK 8
                 Key: LOGMGR-263
                 URL: https://issues.jboss.org/browse/LOGMGR-263
             Project: JBoss Log Manager
          Issue Type: Bug
         Environment: WildFly 17, OpenJDK 11
            Reporter: Andreas Liebscher


During upgrading a Java EE application from WildFly 13 with JDK 8 to WildFly 17 with JDK 11 we had a serious performance issue. We identified the usage of the logging framework SLF4J with the pattern `static Logger log = LoggerFactory.getLogger(StatusChangeValidatorFactory.class)` was the reason when a lot of calls to `getLogger` occur in parallel. As workaround we removed `static` from some code hotspots to get back the performance we were used to. Also WildFly 13 with JDK 8 got a performance improvement with the removed `static` keyword.

Please check the VisualVM output as prove of JDKSpecific got slower:
