(MODULES-2637) Checks java actually installed

Browse Source 
The other method for running which java doesn't work on OSX, as java is installed as an empty shim when not installed in the base OSX image:

```
vagrant:~ vagrant$ java
No Java runtime present, requesting install.
vagrant:~ vagrant$ /usr/libexec/java_home --failfast
Unable to find any JVMs matching version "(null)".
vagrant:~ vagrant$
```

We can use the `/usr/libexec/java_home --failfast` command to check if
java is actually present first.
