[GSS](7.3.z) LOGMGR-263 - Logger Lookup is much slower as with JDK 8

XMLWordPrintable

      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 `Logger log = LoggerFactory.getLogger(XXX.class)` was the reason when a lot of calls to `getLogger` occur in parallel. As workaround we added `static` to some code hotspots to get back the performance we were used to. Also WildFly 13 with JDK 8 got a performance improvement with the added `static` keyword.

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