I should look at the concurrent APIs in javaFX and see if they still set the thread priority…in fact it does. But I haven't noticed any app behavior that changed by doing so. But I haven't tried to set the thread priority from anywhere but within Java, and I'm on a mac, so maybe it works differently (although I am pretty certain I've talked to VM engineers who have said thread priorities are ignored on HotSpot).
