ProxyInfo not available in Tomcat

I'm looking for a way to read proxy informations from within an application deployed on a Tomcat 7.

With the jboss cli I can read the proxies info like this:
/host=xyz/server=abc/subsystem=modcluster:read-proxies-info()

I looked for the ModClusterListener MBean methods and properties in Tomcat 7. I found this method in ModClusterListener:
/**

• {@inhericDoc}

  *

• @see org.jboss.modcluster.ModClusterServiceMBean#getProxyInfo()
  */
  @Override
  public Map<InetSocketAddress, String> getProxyInfo() { return this.service.getProxyInfo(); }

The problem is that I found no proxyInfo method or attribute at the ModClusterListener MBean.
