proxychains4 make hostname to 127.0.0.1

Normal:

root@t2:~# hostname -i
192.168.40.232
root@t2:~# 

Proxy:

root@t2:~# proxychains4 hostname -i
[proxychains] config file found: /usr/local/etc/proxychains.conf
[proxychains] preloading /usr/local/lib/libproxychains4.so
[proxychains] DLL init: proxychains-ng 4.11-git-9-gcf9a16d
127.0.0.1
root@t2:~# 

This lead to:
java rmi server start with proxychains， it's client can't find the remote server, some error like:

Client exception: java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is: 
	java.net.ConnectException: Connection refused

Reproduce the normal and proxychains4 hostname -i commands shown in the report, then compare the proxychains behavior with the Java RMI failure and its 127.0.0.1 connection target. Done should mean hostname resolution does not incorrectly produce loopback and the reported Java RMI client can find the remote server through proxychains4.
