The previous process of deleting referencing entities, updating the root and then inserting referencing entities hat the potential of causing deadlocks. When one process didn't obtain a lock on delete because there wasn't anything to delete root and referencing entities got locks in opposite order, which is a classical cause for deadlocks. Original pull request: #191.

JdbcRepositoryConcurrencyIntegrationTests now only runs with MySql instead of always with MySql. Also modified it to not use sleep. Copyright header added. Formatting. Original pull request: #191.
