HibernateLongIdMatcher (and HibernateStringIdMatcher) is not processed correctly CGLib Enchanced classes -------------------------------------------------------------------------------------------------------- Key: JBPM-846 URL: http://jira.jboss.com/jira/browse/JBPM-846 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.1.3 Reporter: Alexey Kakunin Assigned To: Tom Baeyens Initially I though it is Hibernate Issue and reported it there: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2437 But seems from answer it is bug in jBPM. So, if we storing some object as variable in jBPM, and this object got from Hibernate - and enhanced by CGLib - it is not processed correctly. It is because HibernateLongIdMatcher (and HibernateStringIdMatcher) tried to get meta-data by using object.getClass() - but in this case Class-returned - is not a real class, but class enhanced by CGLib, as result, Hibernate did not returned us MetaData (because cannot find it) and as result - this object stored not as reference - but as BLOB.
