Issue #624: ClassCastException after upgrade to 2.3.5_03

On upgrading to the latest version of objectdb I get the following exception on object retrieval:

The class in question is defined as follows:

@Entity
public class ObjectDbMessagePayload {

@Id String id;


@OneToOne(orphanRemoval=true, cascade=CascadeType.ALL, fetch=FetchType.EAGER)
private Object payload;


@OneToOne(orphanRemoval=true, cascade=CascadeType.ALL, fetch=FetchType.EAGER)
private Map<String, Object> metadata;

...

In this case the "payload" field is a byte[]. This worked ok in 2.3.3_06.

Thank you for this report. Please try build 2.3.5_04 that should fix this new issue.
