/**
* Set the Spring {@link JtaTransactionManager} or the JTA {@link TransactionManager} to be used
* with Hibernate, if any. Allows for using a Spring-managed transaction manager for Hibernate 4's
* session and cache synchronization, with the "hibernate.transaction.jta.platform" automatically
* set to it. Also sets "hibernate.transaction.factory_class" to {@link CMTTransactionFactory},
* instructing Hibernate to interact with externally managed transactions.
*
* <p>A passed-in Spring {@link JtaTransactionManager} needs to contain a JTA {@link
* TransactionManager} reference to be usable here, except for the WebSphere case where we'll
* automatically set {@code WebSphereExtendedJtaPlatform} accordingly.
*
* <p>Note: If this is set, the Hibernate settings should not contain a JTA platform setting to
* avoid meaningless double configuration.
