Today I started a mission to play around with jboss, and I pulled the latest container and tried to get appdynamics to install properly…

registry.redhat.io/jboss-eap-7/eap74-openjdk8-openshift-rhel8:7.4.17-6.1721256395

However, using the default config, I am unable to install the agent and I keep getting the error

I have added this info to the bottom of the standalone.conf file after researching on the internet about how others have had the issue resolve.

JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=org.jboss.byteman,org.jboss.logmanager,com.singularity" 
JAVA_OPTS="$JAVA_OPTS -Djava.util.logging.manager=org.jboss.logmanager.LogManager"
JAVA_OPTS="$JAVA_OPTS -Xbootclasspath/p:$(ls ${JBOSS_HOME}/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-*.jar)"
# JAVA_OPTS="$JAVA_OPTS -Xbootclasspath/p:$(ls ${JBOSS_HOME}/modules/system/layers/base/org/wildfly/common/main/wildfly-common-*.jar)"
JAVA_OPTS="$JAVA_OPTS -Xbootclasspath/p:$JBOSS_HOME/jboss-modules.jar"

for whatever reason, this entry doesn’t seem to be picked up…?

JAVA_OPTS="$JAVA_OPTS -Djava.util.logging.manager=org.jboss.logmanager.LogManager"

I see from all the comments on the internet that this issue has been around for a while now. Has anyone been able to install this agent on the docker image?

Ta,
