jmeter-server fails to start due to 127.0.1.1-binding

[Linus Widströmer]

Description: Ubuntu 10.04 LTS
Release: 10.04
jmeter:
  Installed: 2.3.4-2ubuntu1

Jmetet-server uses InetAddress.getLocalHost() to determine a valid IP address for the host it is running on. It then performs a isLoopbackAddress() on the returned object and fails hard if that is the case.

The problem occurs when a server is configured to use DHCP since, in that case, InetAddress.getLocalHost() returns 127.0.1.1. For RMI the property "java.rmi.server.hostname" can be used but that only resolves half of the problem.

I am attaching a patch which resolved this issue by replacing the trivial InetAddress.getLocalHost() with a method getLocalAddress() which does a more thorough attempt to find a non-loopback address to use.
1) If java.rmi.server.hostname is defined it us used
2) InetAddress.getLocalHost() is attempted
3) Enumerate all network interfaces until a non-loopback ipv4 is found

This patch should be combined with a java.rmi.server.hostname in the jmeter-server script.
