             Summary: Conflict with instances of Karaf for JMX connection
                 Key: KARAF-6534
                 URL: https://issues.apache.org/jira/browse/KARAF-6534
             Project: Karaf
          Issue Type: Bug
          Components: karaf
    Affects Versions: 4.2.4
            Reporter: Julien Greffe


Hello,

when starting two karaf instances with different configurations in {{etc/org.apache.karaf.management.cfg}} shows an error log on the secondly started instance.
{code:java}
Exception in thread "JMX Connector Thread [service:jmx:rmi://0.0.0.0:44444/jndi/rmi://:1099/karaf-root]" java.lang.RuntimeException:
Port already in use: 44444;
You may have started two containers.  If you need to start a second container or the default ports are already in use update the config file etc/org.apache.karaf.management.cfg and change the Registry Port and Server Port to unused ports
        at org.apache.karaf.management.ConnectorServerFactory.lambda$init$0(ConnectorServerFactory.java:275)
        at java.lang.Thread.run(Thread.java:748) {code}

Seems related to this line :
https://github.com/apache/karaf/blob/karaf-4.2.4/management/server/src/main/java/org/apache/karaf/management/internal/Activator.java#L96
which is executed twice at the second instance startup.
