Java exception when performing a query on job streams in plan

If the plan data replication feature (also known as mirroring) is disabled on the master domain manager, there is a time interval that makes a monitoring query fail and the following exception is displayed by the Dynamic Workload Console:
java.lang.UnsupportedOperationException
at
com.ibm.tws.dao.plan.SymphonyJobStreamDAO.queryJobStreams(SymphonyJobStreamDAO.java:1090)
    at com.ibm.tws.conn.plan.PlanImpl.queryPlanObjectPage(PlanImpl.java:2602)

Cause and solution:

This problem occurs if the plan data replication feature (also known as mirroring) is disabled on the master domain manager.

The workaround is to log-out and log-in from the Dynamic Workload Console.
