APAR status
Closed as program error.

Error description
When using the HTTP Transport Handler and a client ends a
request, causing the session (connection) to be closed before
the J2EE server has had the opportunity to read data from the
connection.  This results in an abend0C4 in the application
server control region for method processAsynchIOAccept.

****************************************************************
An ABENDS0C4/ABEND0C4 in
SessionManagerProtocolHTTP::processAsynchIOAccept can occur if
a new Server_HTTPSession object was needed and the asynch read
failed on the socket during the initialization of that object.
The initialization of the object throws an async_net_error if
the asynch read fails.  This is not handled when the
initialization is called from the constructor.
Problem conclusion
The initialization of the Server_HTTPSession object will not be
called from the constructor.  This will enable the logic to
correctly process the throw of the async_net_error. The
initialization(initializeServerHTTPSession) will not be called
from the constructor but will be invoked after the object is
created.
