Initially I had an entity with a basic property marked as lazy (didn't work at first, fixed in HHH-5255).
The another entity was necessary, so I moved some common fields into an embeddable entity, but now the lazy basic property is loaded eagerly.
{code:java}
public class Entity {
// this works
@Basic(fetch = FetchType.LAZY)
private String description;
@Embedded
private RecordData data;
}
@Embeddable
public class RecordData {
// this fails, it is loaded eagerly
@Basic(fetch = FetchType.LAZY)
@Lob
private byte[] content;
}
{code}
If you add a 2-nd field typed {{RecordData}} (as can be seen in my PR), an error in the bytecode enhancer is triggered:
