Hi, JDO spec: final fields are not persisted. How difficult is optionally support final field persistance? Java 5 itself supports this (post-construction modification of final fields is now possible when calling setAccessible(true) on a field via reflection.) Sometimes data must immutable (not altered after creation) - but still persisted. Thanks Toivo |

Why not read http://issues.apache.org/jira/browse/JDO-540 and then if you're so keen on it you can do the work that JIRA required ... ---------------------------------------- -Andy   |

Thanks for link. I'm not competent enough. Does this mean what Datanucleus implements this after next JDO specs include final field persistence? But technically how much final field handling differs form normal field handling in Datanucleus? What kind of synchronization issues may arise? Thank you for your time, Toivo |
