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).
Thanks for your help
Fabian

Hey,
Keep in mind that while WildFly 11 does run fine on JDK9.
It still does that in »classpath« mode not in pure modular(jigsaw) fashion.
As such –patch-module for WildFly modules (jboss-modules) does not apply (yet)
You should be fine by just using your agent with jboss-modules on CP and system property
that James suggested.

to-Xbootclasspath/p:jboss-logmanager-2.0.7.Final.jar in Java 9
There is a system property you need to add to the JAVA_OPTS IIRC. Try adding
"-Dsun.util.logging.disableCallerCheck=true". This should avoid the weird issues
with the log manager.

Hello,
sorry if this is the wrong place to ask, but I am trying to run a Java agent with Wildfly
11 and Java 9. In previous Java versions, I had to add
-Xbootclasspath/p:jboss-logmanager-2.0.7.Final.jar to JAVA_OPTS to make sure the Wildfly
java.util.logging.manager implementation is available to the agent.
I understand that in Java 9 the -Xbootclasspath/p option is replaced with the
--patch-module option. However, I am having trouble to figure out how to use this option.
What is the equivalent to -Xbootclasspath/p:jboss-logmanager-2.0.7.Final.jar is in Java 9
with Wildfly 11?
Thanks a lot
Fabian
