APAR status
Closed as program error.

Error description
A session.removeAttribute results in the attribute being removed
from the session object. In the Database mode the attribute
removal is propagated to the database at the end of the request
and for a time based write it gets sent aynschronously at a
later time.
If customers app removes all the attributes from the session
object and then tries to retrieve an attribute in the same
request the session manager erroneously returns the attribute.
This will occur only if all the attributes were removed from the
session object and before the session manager was able to
propagate the removal to the database.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server users who use   *
*                 the session manager.                         *
****************************************************************
* PROBLEM DESCRIPTION: Session.getAttribute() does not return  *
*                      null when the customer explicitely      *
*                      deletes all the session attributes      *
*                      prior to the getAttribute() method.     *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The session manager was loading all the session values even if
it found that the session object contained no attributes.
Problem conclusion
The correct behaviour is to only load the session attributes
if the load method has not been called.  The session manager
has been corrected to use this new behaviour to load session
attributes and values.

The fix for this APAR is currently targeted for inclusion in
fixpack 5.0.2.12 and 5.1.1.6.  Please refer to the recommended
