Keep getting TypeCastException

[fschon]

I have a basic StringBoot application to test out EclipseStore.

But no matter what I try, the first execution with no storage file works fine and the storage folder is created.
But on the next execution I get a type cast exception on the data root object:

Caused by: org.eclipse.serializer.exceptions.TypeCastException: Cannot cast com.example.data.DataRoot to com.example.data.DataRoot

I have run out of ideas of where to look for this. I tried both the static shared instance as per the Bookstore demo and also the Spring created eclipse store. Can anyone please give me some pointers of where the problem might lie?

Here is what I have so far:

application.properties:

org.eclipse.store.auto-start=true
org.eclipse.store.root=com.example.data.DataRoot

DateRoot.java:

public class DataRoot
{
	private List<String> emails = new ArrayList<>();

	public DataRoot()
	{
	}

	public List<String> emails()
	{
		return this.emails;
	}
}

Emails.java

@Component
public class Emails
{
	private final EmbeddedStorageManager storageManager;


	public Emails(final EmbeddedStorageManager storageManager)
	{
		this.storageManager = storageManager;
	}

	private DataRoot dataRoot()
	{
		return (DataRoot)storageManager.root();
	}

       @Read
	public Optional<String> findByEmail(String email) {
		return dataRoot().emails().stream().filter(t -> t.equals(email)).findFirst();
	}

	@Write
	public void save(String email) {
		dataRoot().emails().add(email);
		storageManager.store(email);
	}
}

And then I have a Spring bean that generates some data:

    @Bean
    public CommandLineRunner testEclipseStore (
            Emails emails
    )
    {
        return args -> {
            var emailsToLoad = List.of("[email protected]", "[email protected]");
            emailsToLoad.stream().forEach(email -> {
                emails.findByEmail(email).ifPresentOrElse(
                        t -> log.info("Email {} already in eclipsestore", t),
                        () -> {
                            emails.save(email);
                            log.info("Email {} added to eclipsestore", email);
                        });
            });
        };
    }
