* commit '4e1afc1a569d05cc6a1ee213c65ffb49513600ca':
  Fixes #1872506. Prevents NPE in ListView. When the opaque property changes at runtime, it is possible to end up in a situation in which the divider's Paint instance has not been instanciated. This change simples uses a final Paint that is guaranteed to not be null.
