I tested your task and basically works well. I found only some details that could be improved.

• There is set the Idm instance name in the property file to e.g. idm-XXX
• If we run IdM and perform provisioning (for example ) we can see that corresponding entity event was executed on current Idm instance ie idm-XXX - setting from file works well
• But in the Configuration page there is still displayed idm-primary.
  This can be very confusing for common users.

• Current instace id is eg. idm.pub.app.instanceId=idm-XXX
• Stop async event processing with idm.sec.core.event.asynchronous.stopProcessing=true
• Set new instance for async operation execution idm.sec.core.event.asynchronous.instanceId=idm-YYY
• Perform a kind of async operation eg provisioning. In entity event table there is a new event creted NOT run. It is planned for idm-YYY Idm instance.
• Start async event processing with idm.sec.core.event.asynchronous.stopProcessing=false
• Check entity event table. The newly created event is EXECUTED on current instance idm-XXX although planned for idm-YYY.

• It acts like situation in the point 2)
• The value is empty in Idm Configuration setting. Value form property file is not propagated to Configuration table. Similar to the point 1)

1. Create simple script (just return constant).
2. Create a LRT executing this script (ExecuteScriptTaskExecutor)
3. Delete this script.
4. Try to reschedule Idm instance for async.

The instance change fails on the following exception. The problem is that it speaks about missing entity but you will be hardly able to find the LRT it pertains to especially in as of many scheduled tasks. I think there could be a specific exception for the task where rescheduling failed with its name. I guess there may be more situations when this may happen.
