Hibernate updates and MySQL 5.0 InnoDB Max
Something else came up today with all this transaction and MySQL stuff. Looks like Hibernate updates do not work unless the session is participating in a transaction when using MySQL InnoDB Max with the default isolation level set to READ-COMMITTED or READ-UNCOMITTED. The tricky part is that inserts work fine but updates never get executed. If you tweak the code and add a transaction or use a Spring annotation or proxy to manage the transaction everything starts working quite nicely.
