                 URL: http://jira.jboss.com/jira/browse/JBPM-846
             Project: JBoss jBPM
          Issue Type: Bug
          Components: Core Engine
    Affects Versions: jBPM 3.1.3

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.

Some possible solutions provided in Hibernate Issue
