I can't connect to JMX server inside Mule using JConsole remote process when the host attribute of management:jmx-default-config is specified as 0.0.0.0.

The remote process URL used in JConsole is:

service:jmx:rmi:///jndi/rmi://localhost:1098/server

Connecting to the local process works just fine.

Using netstat -a -n shows that Mule is listening on port 1098.

Trying to connect remotely doesn't work either by specifying the hostname in the JConsole string, e.g.

service:jmx:rmi:///jndi/rmi://akl0mw304:1098/server

A Wireshark trace shows some network interaction on port 1098 until JConsole closes the socket.

Note that this works fine when specifying JMX via the agents this works fine. For example:

<mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:management="http://www.mulesoft.org/schema/mule/management"

">
<management:jmx-server >
<management:connector-server url="service:jmx:rmi:///jndi/rmi://0.0.0.0:1098/server" rebind="false" />
</management:jmx-server>
<management:rmi-server serverUri="rmi://0.0.0.0:1098" createRegistry="true" />
</mule>
