Passivation of SessionContext field does not work

In case of adding non-transient SessionContext field to a stateful bean, the passivation of the bean ends with exception: JBAS014538: Failed to passivate, Caused by: java.io.NotSerializableException: org.jboss.as.ejb3.context.SessionContextImpl.
(EJB3.1 4.2.1)

Please check my test: https://github.com/ochaloup/jboss-as/blob/JBQA-5483-test-migration-passivation-ctx/testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/ejb/stateful/persistencecontext/StatefulBean.java#L47
