Java methods that were supposed to stay the same are removed after Generated output

[sshaaf]

The class methods are removed. thereby removing the business logic of the class. I can see that the comment states // ... (rest of the class remains the same) however the patch removes the methods.

---- Total Reasoning: ---- 
 To migrate the `DefaultBookingService` class to Quarkus, we need to address the issues related to the `@Stateless` annotation. Since Quarkus uses CDI (Contexts and Dependency Injection) instead of EJBs, we need to replace the `@Stateless` annotation with a CDI scope annotation.

In this case, we can replace `@Stateless` with `@ApplicationScoped`, which is a CDI scope that allows the bean to be instantiated once and shared across the application.

We don't need to make any changes to the imports, as the `jakarta.inject.Inject` annotation is already used, which is compatible with CDI.

---- Used Prompts: ---- 
I will give you a JavaEE file for which I want to take one step towards migrating to Quarkus.

I will provide you with static source code analysis information highlighting an issue which needs to be addressed.

I will also provide you with an example of how a similar issue was solved in the past via a solved example.

You can refer to the solved example for a pattern of how to update the input Java EE file to Quarkus.

Fix only the problem described. Other problems will be solved in subsequent steps so it is unnecessary to handle them now.

Before attempting to migrate the code to Quarkus reason through what changes are required and why.

Pay attention to changes you make and impacts to external dependencies in the pom.xml as well as changes to imports we need to consider.

Remember when updating or adding annotations that the class must be imported.

As you make changes that impact the pom.xml or imports, be sure you explain what needs to be updated.

After you have shared your step by step thinking, provide a full output of the updated file.

Here is another example, As you can see it takes away all the methods but the class is still valid as it adds the closing brace in the end.

Note @sshaaf has seen this behavior with BOTH Bedrock and IBM BAM with llama3. I have seen this behavior with Claude 3.5 sonnet.
