A DESCRIPTION OF THE PROBLEM :
Showing ScrollPane with right conditions causes NPE. Opening window causes focusCleanup() and calls focus traversal listener in the skin and method scrollBoundsIntoView() gets null Bounds as it is not yet ready?

java.lang.NullPointerException: Cannot invoke "javafx.geometry.Bounds.getMaxX()" because "<parameter1>" is null

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Opening Stage with ScrollPane. Unfortunately, I'm unable to provide reproducible example as this happens in a complex form in custom Stage window in complex application. The window showing code is something like this

stage.show()
scene.root = root
stage.sizeToScene()
stage.focus()

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No NPE

Sry, this time unable to provide so far. Would take hours.
