PI82233: NON-DAEMON THREADS ARE CREATED WITH REMOTE EJB USING THE IIOP TRANSPORT

Fixes are available

APAR status

Closed as program error.

Error description

A remote EJB using the IIOP transport causes non-daemon
threads
to be created.  This can cause the JVM to not terminate when
Liberty is shut down.

The non-daemon thread will have a call stack like this:
Java callstack:
at java/net/PlainSocketImpl.socketAccept
at java/net/AbstractPlainSocketImpl.
accept(AbstractPlainSocketImpl.java:450)
at java/net/ServerSocket.implAccept(ServerSocket.java:623)
at java/net/ServerSocket.accept(ServerSocket.java:582)
at org/apache/yoko/orb/OCI/IIOP/Acceptor_impl.
accept(Acceptor_impl.java:126)
at org/apache/yoko/orb/OB/GIOPServerStarterThreaded.

****************************************************************
* USERS AFFECTED:  Users using the embedder API to stop a      *
*                  Liberty server that uses IIOP               *
****************************************************************
* PROBLEM DESCRIPTION: Liberty server hangs indefinitely when  *
*                      stopped via the shutdown API            *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The IIOP listener threads are not daemon threads and prevent the
attached JVM from exiting.

Problem conclusion

The ORB has been modified to use daemon threads for IIOP
listeners.

The fix for this APAR is currently targeted for inclusion in fix
pack 17.0.0.4.  Please refer to the Recommended Updates page for
