We're getting tons of these in production (and in test). OpenJPA
1.0.1 and 1.0.2 :
1677 WARN [main] openjpa.Runtime - Detected possible orphaned
reference to deleted object "125706" in
"com.joost.model.GeneratedThumbnail.videoEnclosure".
In a private chat, Patrick suggested it means that I deleted an
instance of type VideoEnclosure with id 125706, but had refs elsewhere
in the model that I didn't null out
It seems that the data is all there :
mysql> select * from GeneratedThumbnail where videoEnclosureId = 125706;
+--------+------------------+-------------+
| id | videoEnclosureId | captureTime |
+--------+------------------+-------------+
| 125708 | 125706 | NULL |
+--------+------------------+-------------+
1 row in set (0.87 sec)
mysql> select * from Enclosure where id = 125706;
+--------+----------------+---------+------
+--------------------------------------+
| id | itemType | bitRate | sha1 |
p2pId |
+--------+----------------+---------+------
+--------------------------------------+
| 125706 | VideoEnclosure | 346 | NULL | 2eb7b0b4-3619-4d47-
ad84-5ceb36c6385e |
+--------+----------------+---------+------
+--------------------------------------+
1 row in set (0.00 sec)
mysql> select * from VideoEnclosure where id = 125706;
+--------+--------------+----------+-------------+-----------
+-----------+
| id | languageCode | duration | aspectRatio | frameRate |
frameSize |
+--------+--------------+----------+-------------+-----------
+-----------+
| 125706 | 1 | 217384 | 4:3 | 29.970 |
640x480 |
+--------+--------------+----------+-------------+-----------
+-----------+
1 row in set (0.00 sec)
and I don't ever do deletes in this code. Maybe we have broken data
elsewhere the DB - could it be the videoEnclosureId field referenced
in some other entity or class?
Is the joined inheritance strategy widely used and reliable?
