Summary: Broker startup delay when using public NAT IP as JMX RMI
hostname
Key: ARTEMIS-5260
URL: https://issues.apache.org/jira/browse/ARTEMIS-5260
Project: ActiveMQ Artemis
Issue Type: Bug
Environment: Rocky Linux 9.5
ActiveMQ Artemis 2.39.0
Reporter: Vilius Šumskas
If you try to configure JMX remote management in Artemis broker to be reachable
via NAT (for example a broker behind load balancer), there is a 2 minute 10
seconds delay every time the broker is started. Steps to reproduce:
# Create standard Artemis broker instance.
# Enable remote JMX management in management.xml with <connector
connector-port="1099" connector-host="0.0.0.0" rmi-registry-port="1100" />.
# Add -Djava.rmi.server.hostname=8.8.8.8 (or any other IP not under host's
interfaces) to artemis.profile
# Restart the broker and check the delay between

There is no such delay when Artemis' JMX remote management is disabled and the
standard JVM JMX Mbean used instead.
