MetricsSource: if a new job is submitted, PeBean.retrieveMetrics fails

[m-kotowski]

If the test application is running, and a new job is submitted (in this case, the same test app), PeBean.retrieveMetrics raises a NullPointerException.

ERROR #splapptrc,J[0],P[0],ChangeNotifications M[MetricsSource.java:com.ibm.streamsx.metrics.MetricsSource$1.run:357]  - Operator error

Not sure whether this is important but just before the exception is raised, 4 time the following notification is received.

ERROR #splapptrc,J[0],P[0],Numbers M[PeHandler.java:com.ibm.streamsx.metrics.internal.PeHandler.handleNotification:114]  - notification: javax.management.Notification[source=com.ibm.streams.management:type=domain.instance.pe,domain="domain4.2.0.0",instance="streams4.2.0.0",id=1][type=com.ibm.streams.management.pe.changed][message=], userData=null

This problem is solved with IBM Streams 4.2.0.2 fixpack.
