Fixes are available

APAR status

Closed as program error.

Error description

After the last servant region is terminated, the ServerMBean in
the control region will get unregistered. With no ServerMBean in
the control region, the new servant region that gets started in
response to the failed one will not receive the expected
ServerMBean notifications.

response to the failed one will not receive the expected
ServerMBean notifications.

Problem conclusion

J2EE state change notifications are not properly sent
following a Servant Region failover because the ServerMBean
instance is deregistered after all Servant Regions have
terminated. ServerMBean lifecycle is such that there should
only be one instance during the entire life of the
server.
