I'm not be able to create the expected unitary test... However we obtain now a
OptimisticLockException stacktrace instead of ClassCastException (after
applying the patch):

Caused by this loop :
============================
for (AbstractAdminNode<?> node : root.getChildren()) {
if (node instanceof CenterNode) {
CenterNode centerNode = (CenterNode) node;
CenterDAO.getInstance().persist(centerNode.getData()); // <-
exception

Workaround : the code below solves the raised exception.

call em.persistAll(E...)
