> With OpenJDK11 + OpenJ9, I can see following error during the server bootup:
> {code}
> JVMJ9VM085W Malformed option: '-Xlog:gc*:file=<JBOSS_HOME_PATH>/standalone/log/gc.log:time'
> {code}
> Based on the [discussion here|https://github.com/eclipse/openj9/issues/3999], the {{-Xlog:gc}} option is not supported in this JDK and it won't be.
> Relevant part of the startup script for standalone.sh in [upstream WildFly|https://github.com/wildfly/wildfly-core/blob/master/core-feature-pack/src/main/resources/content/bin/standalone.sh#L281].
> 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}}).
