This is a very strange concerning problem and I think it may be a SEVERE
BUG. This post is long but I've tried to include everything necessary to
reproduce the problem. It was very difficult to craft the test code to
reproduce the problem because it's very erratic.
I'm trying to import my test data from flat text files and so I'm
populating foreign keys rather than the objects themselves then calling
PersistenceBroker.retrieveReference(?,?). I'm importing each class of
objects from flat text files one file at a time. The text files contain
the foreign keys and the objects are populated with them. In other
words, I'm not traversing the object graph from top to bottom while
importing but setting the foreign keys such that, after all data is
imported, OJB should have no problem materializing the object graph. The
database was generated by OJB using the autobuild=true property in
OJB.properties. I don't think this problem is related to data contraints
in any way. These are all simple 1:1 associations.
I've pasted in all the code etc below necessary to reproduce the
problem.
Thanks for your help in advance,
-Ken
****THE TEST CODE TO REPRODUCE THE PROBLEM
****IMPORTANT NOTE****
THE LOOP COUNTERS ARE AT 44. ALL DATA IS IMPORTED SUCCESSFULLY IF
COUNTERS ARE <41. BETWEEN 41 AND 51 It FAILS SOMETIMES. >51 IT ALWAYS
FAILS. IF THE LOOP IS MADE INTO ONE LOOP INSTEAD OF TWO, BY COMMENTING
THE TWO LINES BELOW STARTING WITH ****, THEN IT ALWAYS WORKS, EVEN AT
100 LOOPS! WHEN IT FAILS, IT FAILS AT THE LINE MARKED ****FAILS.
