Examples of org.odmg.Transaction.begin()

org.odmg.Transaction.begin()
Start a transaction. Calling begin multiple times on the same transaction object, without an intervening call to commit or abort, causes the exception TransactionInProgressException to be thrown on the second and subsequent calls. Operations executed before a transaction has been opened, or before reopening after a transaction is aborted or committed, have undefined results; these may throw a TransactionNotInProgressException exception.

         TODO: Does not pass - why? A defined lock
         order necessary?
         if this doesn't make sense remove the test
