As part of the fix for JDK-8277785 it is suggested to ignore the test in test.javafx.scene.control.ListViewKeyInputTest.test_rt34407_up_up_down

The final part of this test checks if there are 8 items selected (after a few SHIFT + PAGE_UP/DOWN presses), while with the patch for JDK-8277785 there are only 7 selected items in the viewport.
I do not see any contract violation though, and the 8 therefore seems arbitrary to me.
We should either remove the test, or make it pass and clarify the contract.
