为什么InetAddress.getLocalHost()的这种用法适用于Java 6但在OSX上使用Java 7失败

Question

它适用于我,但在特定客户的OSX Mavericks上,InetAddress.getLocalHost()在Java 7中失败,尽管它在Java 6中运行正常,但有以下异常

java.net.UnknownHostException: rupert: rupert: nodename nor servname provided, or not known
    at java.net.InetAddress.getLocalHost(InetAddress.java:1466)
Caused by: java.net.UnknownHostException: rupert: nodename nor servname provided, or not known
    at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
    at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:894)
    at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1286)
    at java.net.InetAddress.getLocalHost(InetAddress.java:1462)

这是设计的吗？

更新

看起来是Java 8中修复的已知错误

Answer 1

将{yourhostname}部分添加到 /etc/hosts

例如

127.0.0.1       localhost {yourhostname}

问题就消失了.

Answer 2

我猜您会在这里找到答案- 尽管这个问题是关于 Solaris 的，但 Mac OS X 和 Solaris 都是 Unix 操作系统。
