APAR status

• Closed as program error.

Error description

• JNDI Contexts (i.e. javax.naming.Context) in the java:*
  namespaces - java:global, java:app, java:module, and
  java:comp - are not serializable.  This can particularly be
  a problem for stateful session EJBs which would need to be
  able to passivate with a java:* Context for a field instance
  variable. The result would be a NotSerializableException
  which would prevent the EJB from passivating.
