RESOLVED - issue BATCH-262: Hibernate Job blocks on flush

Browse Source 
http://jira.springframework.org/browse/BATCH-262

The hibernate job blocks with high isolatio nlevels because it is reading a cursor and then updating the same objects (the cursor is in a different transaction because it uses openSession()).

The resolution is to change the isolation level - might be worth some more careful work later to encourage the right sort of best practice.
