[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5255) Bytecode instrumented byte[] lazy properties do not work
Bytecode instrumented byte[] lazy properties do not work
--------------------------------------------------------
Key: HHH-5255
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5255
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.2
Environment: Hibernate-3.5.2, Oracle 10g
Reporter: Kyrill Alyoshin
Well, I have an entity that stores a byte[] property as a Blob.
@Lob
@Basic(optional = false, fetch = FetchType.LAZY)
public byte[] getContent() {
return content;
}
The content can be pretty large, so I marked it as lazy and to enable lazy property
fetching I am instrumenting the class at build-time using
org.hibernate.tool.instrument.javassist.InstrumentTask just as the documentation says.
However, when I call session.merge on this entity, I can get this stacktrace:
java.lang.ClassCastException: org.hibernate.intercept.LazyPropertyInitializer$1 cannot be
cast to [B

It seems to work fine on session.get()
I think it is a bug.
