Re: [wildfly-dev] Equivalent to-Xbootclasspath/p:jboss-logmanager-2.0.7.Final.jar in Java 9

Hello, I am sorry, but I still don't get it. My agent initializes the java.util.logging.manager (indirectly, because it registers a JMX bean, and platform MBean server has an internal dependency to logging). This is done before any Wildfly code is loaded. I understand that this works with Wildfly only if the agent uses org.jboss.logmanager.LogManager as the log manager implementation. With Java 8, this can be done with the following start script: cd ./wildfly-10.1.0.Final LOGMANAGER_JAR=$(find $(pwd) -name 'jboss-logmanager-*.jar') export JAVA_OPTS=" -Xbootclasspath/p:${LOGMANAGER_JAR} -Djboss.modules.system.pkgs=org.jboss.logmanager,io. promagent.agent -Djava.util.logging.manager=org.jboss.logmanager.LogManager -javaagent:promagent.jar=port=9300 " ./bin/standalone.sh The question is, how do I make jboss-logmanager-2.0.7.Final.jar available to the agent's class loader with Java 9? The "-Xbootclasspath/p:" option was removed, but the agent needs access to the org.jboss.logmanager.LogManager class to initialize logging correctly (Wildfly doesn't seem to run when the agent initializes logging with the default log manager).

Try adding "-Dsun.util.logging.disableCallerCheck=true".
