Subject [jira] Commented: (OPENJPA-1249) Rework Oracle LOB support
Date Thu, 17 Sep 2009 17:35:57 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756641#action_12756641
] 

Jeremy Bauer commented on OPENJPA-1249:
---------------------------------------

While investigating a failing test I found that the default dictionary method for initializing
a blob input stream was not working for Oracle, resulting in an NPE.  It appears that the
signature of the base dictionary method had been updated at some point, but the Oracle override
had not, resulting in the base method getting called.  (Annotating with @Override would have
flagged the error at compile time.)  This corrected several failures but a few remain.  Those
will be addressed separately.  The fix in rev 816287 does not address the base requirement
of this JIRA, but  is a step toward that goal.

> We could probably get rid of the following Oracle-specific behaviour and code:
> - using non-embedded LOB handling when size of the value exceeds 4000 bytes/chars,
> - using empty LOB when persisting a null value.
> Chances are the above behaviour is not needed starting from Oracle 9 or 10.
