Examples:

• I cannot use a receive task as a compensation handler: no message event subscription is created
• I cannot use a subprocess as a compensation handler that has an (timer/message) event subprocess: the subscription/job for the event subprocess is never created

Reason:

• the event scope execution is not initialized (to create event subscriptions etc) before executing the compensation handling activity
