Gustavo Lopes updated OPENJPA-2312:
-----------------------------------

    Attachment: details.txt

Spring conf, persistence unit and log. I insert one row in two tables, do a 
select, and afterwards manually issue a rollback and and a conflicting insert. 
The insert fails due to a unique constraint violation. If I proxy the single 
connection so that setAutoCommit(true) is suppressed, then the insert succeeds.
                
> H2 is forced to autoCommit; breaks transactions
