void removeComponentInfo(JID componentJID) {
        // Remove any info stored with the component being removed
        componentInfo.remove(componentJID.getDomain());
    }
Removes a given component. Unlike {@link #removeComponent(String)} this method will just
remove a single component instead of all components associated to the subdomain. External
components may connect several times and register for the same subdomain. This method
just removes a singled connection not all of them.

@param subdomain the subdomain of the component's address.
@param component specific component to remove.
