REGRESSION : Last worked in version 8u431

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
 private void synchronizeSceneNodes() {
            Toolkit.getToolkit().checkFxUserThread();

            Scene.inSynchronizer = true;

            // if dirtyNodes is null then that means this Scene has not yet been
            // synchronized, and so we will simply synchronize every node in the
            // scene and then create the dirty nodes array list
            if (Scene.this.dirtyNodes == null) {
                // must do this recursively
                syncAll(getRoot());
                dirtyNodes = new Node[MIN_DIRTY_CAPACITY];

            } else {
                // This is not the first time this scene has been synchronized,
                // so we will only synchronize those nodes that need it
                for (int i = 0 ; i < dirtyNodesSize; ++i) {
                    Node node = dirtyNodes[i];
                    dirtyNodes[i] = null;
                    if (node.getScene() == Scene.this) {
                            node.impl_syncPeer();
                        }
                    }
                dirtyNodesSize = 0;
            }

            Scene.inSynchronizer = false;
        }

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
 private void synchronizeSceneNodes() {
            Toolkit.getToolkit().checkFxUserThread();

            Scene.inSynchronizer = true;

            // if dirtyNodes is null then that means this Scene has not yet been
            // synchronized, and so we will simply synchronize every node in the
            // scene and then create the dirty nodes array list

ACTUAL -

            Scene.inSynchronizer = true;

            // if dirtyNodes is null then that means this Scene has not yet been
