================================== Ai Message ==================================

Based on the provided differences in ASTs and the list of issues, I will analyze the changes and identify any issues that are not fixed.

The issue is to replace the `@MessageDriven` annotation with a CDI scope annotation like `@ApplicationScoped`. 

In the provided differences, I see that the `@MessageDriven` annotation has been removed from the `OrderServiceMDB` class. However, I do not see any evidence of the `@ApplicationScoped` annotation being added to the class. 

Therefore, I believe that this issue is not fixed.

Additionally, I notice that the `OrderServiceMDB` class has been removed entirely, and there is no indication of a new class being created to replace it. This suggests that the functionality of the `OrderServiceMDB` class has been removed, which may be a change in the original functionality.

New changes that were not originally mentioned in the issues include the removal of the `OrderServiceMDB` class and the addition of new imports and classes.

Unnecessary changes include the removal of the `OrderServiceMDB` class, which may have been a necessary part of the original functionality.

In conclusion, I believe that the issue is not fixed, and there are new changes that were not originally mentioned in the issues.
