> Maybe MNG-5658 is related to this problem. {{/usr/libexec/java_home}} is a command([java_home(1)|https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man1/java_home.1.html]),
and {{$(command)}} is a style of [Command Substitution|http://www.tldp.org/LDP/abs/html/commandsub.html]
(Another(old) style is {{`command`}}).
> So removing "$()" breaks the JAVA_HOME detection on OS X.
