Description

Setting rmiServerHost/rmiRegistryHost to 0.0.0.0 no longer allows connections from remote hosts:

$>open service:jmx:rmi://10.11.12.13:44444/jndi/rmi://10.11.12.13:1099/karaf-root -u karaf -p karaf
#RuntimeIOException: Runtime IO exception: no such object in table 

...but allows from actual host:

$>open service:jmx:rmi://10.11.12.13:44444/jndi/rmi://10.11.12.13:1099/karaf-root -u karaf -p karaf
#Connection to service:jmx:rmi://10.11.12.13:44444/jndi/rmi://10.11.12.13:1099/karaf-root is opened

This behavior changed somewhere between 4.2.10 and 4.2.15 (im guessing https://issues.apache.org/jira/browse/KARAF-6955)

Setting rmiServerHost/rmiRegistryHost to the interface IP (10.11.12.13) works around the issue, but then ports 1099/44444 are bound to that interface.
