Both your original code as the patch you mention above work. I'm unsure what is 
the best (most elegant and most consistent approach).

The code in `com.sun.glass.ui.Platform` first checks if the property 
*"glass.platform"* is set, and only if that is not set, there is a fallback to 
`PlatformUtil`. 

`PlatformUtil` relies mainly on the value of the System Property *"os.name"*. 

But I believe there is an inconsistency in `PlatformUtil`. Some of the code 
uses the "glass.platform" as well, and I think that goes against the idea that 
"glass.platform" is glass-specific, where glass is part of the 
`javafx.graphics` module, hence it should be used in the `javafx.graphics` 
module, and *not* in the `javafx.base` module.
That would require a major refactory, where the overlap between the javafx.base 
`PlafformUtil` and the javafx.graphics `Platform` is removed.
@kevinrushforth Do you have any thoughts about this?

Since the current proposed PR is simple and useful (using `headless` instead of 
`Headless` should work indeed), I am ok with this PR, unless there is an easy 
solution that provides more consistency?
