This results in the error above saying the file is not a valid Win32 application.

I have absolutely no clue why this happens, especially since the encoded jnlp_content of the Webstart link is exactly the same as both the encoded jnlp_content of the embedded JavaFX application & the external BrickBreaker.jnlp file.
