Java 8 Pitfall

localhost hostname 오류

https://bugs.openjdk.java.net/browse/JDK-8062840
/etc/hosts에 127.0.0.1 localhost 존재시 올바른 hostname이 아닌 무조건 localhost 리턴
[JRA-39070] JIRA from address in outbound email changed to 'localhost' if you use Java 8 - Atlassian JIRA
- If /etc/hosts is 127.0.0.1 localhost localhost.localdomain centos57, then Java8 returns localhost for getHostName().
- If we rewrite this as 127.0.0.1 centos57 localhost.localdomain localhost then getHostName() returns centos57.
