APAR status
Closed as program error.
Error description
Even though the customer uses waitForAll API of CommonJ so that it wait for the completion of all works, there is a chance that WorkItem.getResult returns null even after waitForAll returns true. This behavior may cause the unexpected NPE in the customer's asyncbean application.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of CommonJ WorkManager in IBM * * WebSphere Application Server * **************************************************************** * PROBLEM DESCRIPTION: Timing window after waitForAll where * * getResult returns null * **************************************************************** * RECOMMENDATION: * **************************************************************** There is a small timing window after the WorkManager waitForAll method returns indicating all work is complete where querying a WorkItem's getResult method can return NULL, indicating that the work is not yet complete.

Code fixed to avoid the timing window. The fix for this APAR is currently targeted for inclusion in fix pack 9.0.0.11 and 8.5.5.16. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
