Relevant part of the startup script for standalone.sh in [upstream WildFly|https://github.com/wildfly/wildfly-core/blob/master/core-feature-...]. This warning occurs only on OpenJDK11 + OpenJ9. This does not show up when using OpenJDK8 + OpenJ9 as different branch in script is used in that case ({{-verbose:gc -Xloggc:\"$JBOSS_LOG_DIR/gc.log\" -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=3M -XX:-TraceClassUnloading}}).
