APAR

APAR status
Closed as program error.

Error description

between client and server, so they will correctly interoperate
with WebSphere/390.

SessionHandle
EntityHandle
EJBMetaData
FinderEnumeration
EntityHomeHandle
RemoteIterator
possibly others TBD

Problem summary
****************************************************************
* USERS AFFECTED: All WebSphere Application Server users of    *
*                 getEJBMetaData, getHandle, getHomeHandle,    *
*                 and finders (Enumeration returning or        *
*                 Collection returning).                       *
****************************************************************
* PROBLEM DESCRIPTION: Serialization errors occurred when      *
*                      calling getEJBMetaData on homes.        *
*                      Also Serialization errors occur         *
*                      while calling getHandle on              *
*                      EJBs.                                   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
There were basically two reasons this failed.
One was that the Container didn't code the serializable classes
which had problems according to the java spec.  This resulted in
a variety of symptoms, such as mis-matched serialization UIDs,
underlying bridge exceptions, and invalid chunk size exceptions.
.
Once the container team fixed their code, it was discovered
that the jdk orb had problems as well.  These problems are fixed
in 3.5.6 and 4.0.3 in the jdk's which shipped with those ptfs.
Problem conclusion
The implementations for Handles, HomeHandles, FinderEnumerators,
FinderEnumerations, and EJBMetaData were changed to conform to
the java serialization guidelines.  This was done for 3.5.6
and 4.0.3.  zSeries also did the same.
