```
$ sw_vers -productVersion
10.7.5
$ /usr/libexec/java_home
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
```
```
$ sw_vers -productVersion
10.9
$ /usr/libexec/java_home
Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.
