Josh Oddman commented on Bug LOGBACK-749
> What is the output of "scutil --get HostName" on your system?

HostName: not set

> This issue doesn't appear to be a problem with logback, per se [1]
May be it's java 7 bug, but it's difficult to fix bug in java code and force all users to update JDK. For my application it's not an option.
Reasonable solution is to make logback works with it (use Ralph fix for example).
