/**
 * Implementation of class used to create a subordinate BA transaction
 *
 * This class normally redirects all calls to call the corresponding method of the singleton instance
 * which implements UserBusinessActivity. In the case of a begin call it redirects to a beginSubordinate call
 * on the UserBusinessActivity singleton. In the case of a complete, cancel or compensate it throws a
 * WrongStateException, irrespective of whether the current transaction is top-level or subordinate since
 * these operations should only be attempted via the UserTransactionImple singleton obtained by calling
 * TransactionFactory.userTransaction()
