How come all documentation I read does not say EM is thread safe at all? EM with transactional type is the default type right?
Even in that case, if 2 threads try to update or read the same entity there is a chance of data corruption because the lock is readOnly. Not sure how would that affect isolation level and optimistic locking. -- View this message in context: http://openejb.979440.n4.nabble.com/ConcurrentAccessTimeoutException-tp4661288p4661471.html Sent from the OpenEJB User mailing list archive at Nabble.com.
