Quoting Anthony Petrov:
"Note that the corresponding code in Scene.java that throws the exception is now located at another lines due to other changes to that file. Nevertheless, the piece of code that actually throws it looks like this:

                for (int i = 0 ; i < dirtyNodesSize; ++i) {
                    Node node = dirtyNodes[i];
                    dirtyNodes[i] = null;
                    if (node.getScene() == Scene.this) {
                            node.impl_syncPeer();
                        }
                    }

There's a missing null check before using the node variable in the if() condition."
