regression: jdk1.7.0_04 java.net.InetAddress.getLocalHost().getHostName() return FQHN

[Wolfgang Hoschek]

Hi Alan,

Thanks for letting me know. I strongly encourage you all to revert the behavioral change on Linux and Mac not just in jdk8 but also in jdk7u as well. This critical java regression prevents us from upgrading to jdk1.7.0_04. 

Best regards,
Wolfgang.

This is a regression wrt. all prior versions of jdk 1.7 and jdk 1.6. This breaks applications that expect the old behavior.

However there was a behavior change on Linux and Mac in 7u4 and jdk8 that came via the addition of the Mac port. He has already been fixed in jdk8 as 7166687 [1] and I believe Rob intends to get it into jdk7u too.
