After analysis I don't find the ch.qos.logback.classic.boolex.GEventEvaluator class under the embedded  logback-classic 1.2.11 jar.  Here's the console output proving it: {code:java} java.lang.IllegalStateException: Logback configuration error detected: ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [evaluator] of type [ch.qos.logback.classic.boolex.GEventEvaluator] java.lang.ClassNotFoundException: ch.qos.logback.classic.boolex.GEventEvaluator {code} So Why this implementation was deleted? I didn't find a replacement for it in your documentation. Any help will be appreciated.  It's not a bug. ============================== This message was sent by Atlassian Jira (v8.8.0#808000-sha1:e2c7e59)
