ClassCastException when stopping an application containing a microflow

The SystemOut.log file contains ClassCastException exceptions around the time when an application containing a microflow had been stopped.

Reason

When an application is stopped, the classes contained in the EAR file are removed from the class path. However, microflow instances that need these classes may still be executing.

Resolution

Perform the following actions:
  1. Stop the microflow process template first. From now on, it is not possible to start new microflow instances from that template.
  2. Wait for at least the maximum duration of the microflow execution so that any running instances can complete.
  3. Stop the application.
