IPv issues with Java 8

[Nilhcem]

"If I want to use FakeSMTP with Java 8, I have to specify that it should use the IPv4 stack instead of the IPv6 stack. Otherwise, FakeSMTP doesn’t work properly."

Hello @Nilhcem,

I would like to look at the issue. Could you please tell me how to reproduce it? I have Java 8 (I am using OS X currently with Java 8 (51)), and integration tests work fine.

This is what I see in logs:

28 Jul 2015 21:05:09 INFO  org.subethamail.smtp.server.SMTPServer - SMTP server *:2525 starting
28 Jul 2015 21:05:09 INFO  org.subethamail.smtp.server.ServerThread - SMTP server *:2525 started

Kind regards,
Vest

Hm. It seems that I haven't tested all features properly. If you start the data binding on localhost:2525, the server starts well. However after the integration tests run, the exception below is thrown:

java -jar fakeSMTP-2.1-SNAPSHOT.jar -a 127.0.0.1 -b -s -p 2525

Hello!

I'm started FakeSMTP
java -jar fakeSMTP-2.0.jar --start-server --port 2525 --bind-address 127.0.0.1
27 окт 2016 02:43:45 INFO org.subethamail.smtp.server.SMTPServer - SMTP server *:2525 starting
27 окт 2016 02:43:45 INFO org.subethamail.smtp.server.ServerThread - SMTP server *:2525 started

and view:
netstat -apn | grep 2525
tcp6 0 0 :::2525 :::* LISTEN 18744/java

java -jar fakeSMTP-2.0.jar -b --start-server --port 2525 --bind-address 127.0.0.1
27 окт 2016 02:44:51 INFO org.subethamail.smtp.server.SMTPServer - SMTP server /127.0.0.1:2525 starting
27 окт 2016 02:44:51 INFO org.subethamail.smtp.server.ServerThread - SMTP server /127.0.0.1:2525 started

and view:
netstat -apn | grep 2525
tcp6 0 0 127.0.0.1:2525 :::* LISTEN 18866/java

tcp6 only? why? This may be fixed?
