While manipulating nodes in a rather complex scene I hit this exception as the node count and scene graph "depth" (nested levels of nodes) was increasing. Once it happended the first time, layout was constantly throwing from the same point it seemed and then the stack traces stopped printing entirely an I just got "Exception in thread "JavaFX Application Thread" java.lang.ArrayIndexOutOfBoundsException" without a stack trace repeatedly printing to the console whenever I interacted with the app.
