plans to make JavaFX 8 platform independent again?

Hi Stefan,

Java and JavaFX are platform-independent, so asking whether we will 
"make it platform-independent again" is asking the wrong question. 
Really, your question should be:  can a fix for a serious bug be 
backported to JDK 8 after it is fixed in JDK 9. The answer to that 
question is "yes" for serious bugs and regressions.

What you have discovered in this case is a serious bug that happens to 
affect a single platform. In fact, my reading of the bug is that we are 
just getting lucky on the other platforms. If this turns out to be as 
serious as it seems, then I will bump the priority to P2 and we will 
consider a backport to a JDK 8 update release.
