David Schmitt dadc7a6c22 (MODULES-2637) Checks java actually installed
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.

# Fact: java_version
#
# Purpose: get full java version string
#
# Resolution:
# Tests for presence of java, returns nil if not present
# returns output of "java -version" and splits on \n + '"'
#
# Caveats:
# none
#
# Notes:
# None
Facter.add(:java_version) do
# the OS-specific overrides need to be able to return nil,
# to indicate "no java available". Usually returning nil
# would mean that facter falls back to a lower priority
# resolution, which would then trigger MODULES-2637. To
# avoid that, we confine the "default" here to not run
# on those OS.
# Additionally, facter versions prior to 2.0.1 only support
# positive matches, so this needs to be done manually in setcode.
