Nope, not even in 7.2.
I kinda suspect that you are getting confused by JDBC autocommit
behavior and are having transactions commit when you thought they
were still open. But without a complete example it's only speculation.
Your first gripe might also be explained by supposing that the
transactions are actually in read committed mode, and not serializable
mode at all.
