Apmosys,

Verify your JVM startup options as given in the below link and see if you have added the below startup settings.

https://docs.appdynamics.com/display/PRO42/JBoss+and+Wildfly+Startup+Settings

Linux

In Linux, you can populate the path dynamically with the following code: 

JBOSS_MODULES_SYSTEM_PKGS ="org.jboss.byteman,com.singularity,org.jboss.logmanager"

JAVA_OPTS="$JAVA_OPTS -Djava.util.logging.manager=org.jboss.logmanager.LogManager"
JAVA_OPTS="$JAVA_OPTS -Xbootclasspath/p:$(ls ${JBOSS_HOME}/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-*.jar)"

If using the ${JBOSS_HOME} variable, as in the example, be sure to set the variable to the directory to the JBoss installation directory on your system. 

The path to the LogManager JAR file under the JBoss home can vary by JBoss version. Be sure to check your system and adjust the path as shown in the example accordingly. 

Regards,

Mohammed Rayan
