public boolean isDirty(
Object old,
Object current,
SessionImplementor session) throws HibernateException {
if ( isSame( old, current ) ) { return false; }
Object oldid = getIdentifier( old, session );
Object newid = getIdentifier( current, session );
return getIdentifierType( session ).isDirty( oldid, newid, session );
}
return getIdentifierType( session ).isDirty( oldid, newid, session );
==>
return getIdentifierOrUniqueKeyType( session ).isDirty( oldid, newid, session );
for property-ref in xml
getIdentifierType( session ) return identity type of the associated entity
instead of what the property-ref property type is expected
ADD:
Object oldid = getIdentifier( old, session );
Object newid = getIdentifier( current, session );
getIdentifier() process the property-ref perfectly

Very Important：
this exception occurred only when the identifier type of the associated entity is BigDecimal(and other type which's TypeDescriptor override the "areEquals" method of AbstractTypeDescriptor)
