Hibernate version: 2.1.8

Mapping documents:
<class name="Foo" lazy="true">
...
</class>

Code between sessionFactory.openSession() and session.close():
foo=session.get(id);
assertTrue(foo instanceof HibernateProxy);//foo is a proxy
newFoo=org.apache.commons.beanutils.BeanUtils.cloneBean(foo);//error!

Full stack trace of any exception that occurs:
java.lang.NoSuchMethodException: Property 'callback' has no getter method
at org.apache.commons.beanutils.PropertyUtils.getSimpleProperty(PropertyUtils.java:1180)
at org.apache.commons.beanutils.PropertyUtils.copyProperties(PropertyUtils.java:318)
at org.apache.commons.beanutils.BeanUtils.cloneBean(BeanUtils.java:167)


Name and version of the database you are using:
oracle9i

The generated SQL (show_sql=true):
none

Debug level Hibernate log excerpt:
none

Exception occures when cloning a lazy-load-persistent object by BeanUtils.
I think this error comes from CGLib or BeanUtils, not Hibernate,
but developer always use BeanUtils and Hibernate together.
Any suggestion?

You can "unproxy" bean before to clone, there is API for this stuff.

Thanks.
Unproxy is the only way.
But it means that proxy(when session is still opening) is an invalid bean!
