/**
+ * Reproduce issue posted by user:
+ * Consider A1 and B1 cross referenced objetcs, each one referring the
other.
+ The process consists with create A2, and replace A1.
+ So, with ODMG, we wrote something like that :
+ 1. retrieve A1, retrieve B1 with A1.getB()
+ 2. instanciation and lock of A2
+ 3. A2.setB(B1)
+ 4. delete A1 (markDelete)
+ 5. lock B1, B1.setA(null)
+ 6. flush (assume it is required)
+ 7. lock B1
+ 8. B1.setA(A2)
+ 9. commit
+ After commit, we observed that in database, B1 doesn't refers A2 !!
