ADDITIONAL SYSTEM INFORMATION :
Windows 10 host
Mac OS 10.13 guest
setup like this https://techsviewer.com/install-macos-high-sierra-virtualbox-windows/
VirtualBox 6.0

A DESCRIPTION OF THE PROBLEM :
When I run my JavaFX application on Mac OS 10.13 when its a guest OS on VirtualBox I get w window with is blank - has no UI controls.

You can see the final effect here: https://walczak.it/application/files/6015/7299/2981/javafx-mac-bug.png

Before the window appears I can see the following errors in the console:

2019-11-05 14:34:55.138 java[453:5374] CGLChoosePixelFormat error: 10002
2019-11-05 14:34:55.138 java[453:5374] CGLCreateContext error: 10002

After reading this: https://stackoverflow.com/questions/29653934/are-there-known-incompatibilities-that-prevent-javafx-from-running-in-a-virtuali
i tried adding this to my build.gradle

run {
    jvmArgs '-Dprism.order=sw'
}

and runned my app via

./gradlew run -Dprism.order=sw

but it did not help.

All this seam a a regression of https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8154148
