When one federated system is not reachable, the Process Federation Server REST API might return an HTTP 500 error and multiple FFDC log entries related to NullPointerExceptions, similar to the following examples, might be generated in the Process Federation Server logs/ffdc directory: Exception = java.lang.NullPointerException Source = com.ibm.bpm.federated.query.rest.impl.SystemStatusThread probeid = 1007 Stack Dump = java.lang.NullPointerException at com.ibm.bpm.federated.query.rest.impl.SystemStatusThread.call(Un knownSource) at com.ibm.bpm.federated.query.rest.impl.SystemStatusThread.call(Un knownSource) at java.util.concurrent.FutureTask.run(FutureTask.java:267) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExec utor.java:1143) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExe cutor.java:618) at java.lang.Thread.run(Thread.java:785) ---------------------------------------------- Exception = java.lang.NullPointerException Source = com.ibm.bpm.federated.query.rest.impl.GroupLookupThread probeid = 1004 Stack Dump = java.lang.NullPointerException at com.ibm.bpm.federated.query.rest.impl.GroupLookupThread.updateUs erGroupInfo(Unknown Source) at com.ibm.bpm.federated.query.rest.impl.GroupLookupThread.call(Unk nown Source) at com.ibm.bpm.federated.query.rest.impl.GroupLookupThread.call(Unk nown Source) at java.util.concurrent.FutureTask.run(FutureTask.java:267) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExec utor.java:1143) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExe cutor.java:618) at java.lang.Thread.run(Thread.java:785) PRODUCTS AFFECTED IBM Business Process Manager (BPM) Advanced IBM BPM Standard IBM BPM Express
Local fix
Problem summary
No additional information is available.
Problem conclusion
A fix will be available in IBM BPM V8.5.7 cumulative fix 2017.03 that prevents the Process Federation Server retriever component from throwing NullPointerExceptions when a federated system is not reachable. With the fix applied, the Process Federation Server REST APIs no longer returns an HTTP 500. As expected the API returns the consolidated data it obtained from the federated systems and indicates the system it couldn't reach.
Temporary fix
Not applicable.
