RFR: JDK-8248122: java.base should not handle JavaFX application in a specific way

[Kartik Ohri]

Hi!
I was unable to add the openjfx to the PR on github and was unsure which
other mailing list is right for discussing this change, hence I am sending
it here. If this is the wrong mailing list, pardon me and kindly point me
in the right direction.

The related pull request is https://github.com/openjdk/jdk/pull/978 and the
webrev is available at
https://openjdk.github.io/cr/?repo=jdk&pr=978&range=00.

Thank you.
Regards,
Kartik
