JMX Interface not removable

[stephangoeldi]

In a Host configuration I added a JMX Interface, since there is Tomcat running on some ports.
It doesn't work though (Connection refused: service:jmx:rmi:///jndi/rmi://127.0.0.1:8005/jmxrmi).
I cannot remove the interface, because the remove-link is grey and not clickable.

How can I remove this interface? Why does the remove-link not work?

Interface cannot be removed, if there are items connected to it. Remove items (template) from host and IF should become removable.
