> DatabaseDescriptor throws NPE when rpc_interface is used

> Copy from mail to dev mailinglist.
> When using
> - listen_interface instead of listen_address
> - rpc_interface instead of rpc_address
> starting 2.1.3 throws an NPE:
> {code}
> ERROR [main] 2015-02-20 07:50:09,661 DatabaseDescriptor.java:144 - Fatal

> {code}
> I think that listenAddress in the second else block is an error. In my case
> rpc_interface is eth0, so listenAddress gets set, and rpcAddress remains
> unset. The result is NPE in line 411:
> {code}
> if(rpcAddress.isAnyLocalAddress())
> {code}
> After changing rpc_interface to rpc_address everything works as expected.
