Subject [jira] Created: (AMQ-2594) Make JDBC store resilient on broker sequence id order

Make JDBC store resilient on broker sequence id order

                 Key: AMQ-2594
             Project: ActiveMQ
          Issue Type: Improvement
    Affects Versions: 5.3.0
            Reporter: Dejan Bosanac
            Assignee: Dejan Bosanac
             Fix For: 5.3.1, 5.4.0

Currently if the message is sent in a transaction, there's a chance that messages are added
to the cursor out of order (regarding broker seq id). The problem with JDBC store is that
it does message recovery based on this seq id, which can lead to all kind of problems (such
as orphaned messages in the database).

The solution is to refactor JDBC store to use its own seq generator for recovering purposes
and replace broker seq id, with message id for all other operations
