+     * Test for OJB-103
+     *
+     * 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 !!
