# On Mac OS X, the development tools include "stubs" for JVM executables that
# prompt the user to install the JVM if they desire. In our case we simply
# wish to detect if the JVM is there and do not want to trigger a popup
# window. As a workaround, we can run the java_home executable and check its
# exit status to determine if the `java` executable is the real one or the OS
# X stub. In the terminal, it looks like this:
#
# $ /usr/libexec/java_home
# Unable to find any JVMs matching version "(null)".
# No Java runtime present, try --request to install.
#
# $ echo $?
# 1
#
# This check always returns true when not on darwin because it is just a
# workaround for this particular annoyance.
