Duplicate command handler resolver is triggered in polymorphic aggregates

[CodeDrivenMitch]

Basic information

• JDK version: -
• Complete executable reproducer if available (e.g. GitHub Repo): -

Steps to reproduce

• Create a class annotated with @Aggregate.
• Create subclasses of this aggregate, also annotating them.
• The application will trigger the duplicate command handler resolver.

Expected behaviour

Actual behaviour

After testing this with the customer, it has not been fixed. The testcase provided in the PR was wrong. The aggregate structure which caused the issue looks like this:

@SuppressWarnings("unused")
abstract class RootAggregate {
    @CommandHandler
    public void handle(String command) {
    }
}
class ChildAggregate extends RootAggregate {
    @CommandHandler
    @Override
    public void handle(String command) {
    }
}

I am reopening the issue and targeting the correct fix for the 4.5.x branch
