Error description
During server shutdown a CWOBB9999E error message is logged in SystemOut.log referencing the following stack: java.lang.NullPointerException at com.ibm.ws.bbson.interest.InterestManagerImpl$InterestAlarmL istener.sendMsgs(InterestManagerImpl.java:1264) at com.ibm.ws.bbson.interest.InterestManagerImpl$InterestAlarmL istener.alarmWork(InterestManagerImpl.java:1165) at com.ibm.ws.bbson.interest.InterestManagerImpl$InterestAlarmL istener.alarm(InterestManagerImpl.java:1068) at com.ibm.ejs.util.am._Alarm.runImpl(_Alarm.java:151) at com.ibm.ejs.util.am._Alarm.run(_Alarm.java:136) at com.ibm.ws.util.ThreadPool$Worker.run(ThreadPool.java:1892) The NullPointerException occurred because when the shutdown sequence executed BBSON was running an alarm thread responsible for broadcasting bulletin board messages over P2P/SON and P2P/SON was already down when BBSON tried to interact it. There is no side effects to this condition because the messages that would have been sent are thrown away when BBSON itself shutdown and cancels all of its alarm threads.

There is no side effects to this condition because the messages that would have been sent are thrown away when BBSON itself shutdown and cancels all of its alarm threads.
Problem conclusion
The BBSON code was altered to avoid encountering the java.lang.NullPointerException during shutdown when one of its alarm threads is running simultaneously. The fix for this APAR is currently targeted for inclusion in fix packs 8.5.5.14 and 9.0.0.9.
