The Hashtable and AbstractMap classes have no common ancestor yet may |

be handled with a single persistence delegate: one which uses the methods |

305 |
of the Map insterface exclusively. Attatching the persistence delegates |

306 |
to the interfaces themselves is fraught however since, in the case of |
|
307 |
the Map, both the AbstractMap and HashMap classes are declared to |

308 |
implement the Map interface, leaving the obvious implementation prone |
|
309 |
to repeating their initialization. These issues and questions around |

310 |
the ordering of delegates attached to interfaces have lead us to |

311 |
ignore any delegates attached to interfaces and force all persistence |

delegates to be registered with concrete classes. |
