/**
 * 

The javax.transaction.Transactional annotation provides the application * the ability to declaratively control transaction boundaries on CDI managed beans, as * well as classes defined as managed beans by the Jakarta EE specification, at both the class * and method level where method level annotations override those at the class level.

*

See the Jakarta Enterprise Beans specification for restrictions on the use of @Transactional with Jakarta Enterprise Beans.

*

This support is provided via an implementation of CDI interceptors that conduct the * necessary suspending, resuming, etc. The Transactional interceptor interposes on business method * invocations only and not on lifecycle events. Lifecycle methods are invoked in an unspecified * transaction context.

*

If an attempt is made to call any method of the UserTransaction interface from within the * scope of a bean or method annotated with @Transactional and a Transactional.TxType other than * NOT_SUPPORTED or NEVER, an IllegalStateException must be thrown. The use of the UserTransaction * is allowed within life cycle events. The use of the TransactionSynchronizationRegistry is allowed * regardless of any @Transactional annotation.

*

The Transactional interceptors must have a priority of * Interceptor.Priority.PLATFORM_BEFORE+200. * Refer to the Interceptors specification for more details.

*

The TxType element of the annotation indicates whether a bean method is to be executed within * a transaction context. TxType.REQUIRED is the default.

* *

By default checked exceptions do not result in the transactional interceptor marking the * transaction for rollback and instances of RuntimeException and its subclasses do. This default * behavior can be modified by specifying exceptions that result in the interceptor marking the * transaction for rollback and/or exceptions that do not result in rollback.

*

The rollbackOn element can be set to indicate exceptions that must cause the interceptor to mark * the transaction for rollback.

*

Conversely, the dontRollbackOn element can be set to indicate * exceptions that must not cause the interceptor to mark the transaction for rollback.

*

When a class is specified for either of these elements, the designated behavior applies to subclasses * of that class as well. If both elements are specified, dontRollbackOn takes precedence.
