ArrayindexoutOfBoundsException from Parent.updateCachedBounds

While porting an application from JavaFX 2.2 to JavaFX8, I get an ArrayIndexOutOfBoundsException.
It comes from the for-loop within Parent.updateCachedBounds: It keeps counting down beyond 0, as one of my dirtyNodes seems to have node.boundsChanged==false. Looking at the code, the for-loop seems to lack a guard against this condition.
