    Description

      Environment (Required on creation):

      Camunda Automation Platform 7.16.7

      Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

      A non-interrupting Timer Start Event in an event subprocess fires again after migration.

      Steps to reproduce (Required on creation):

      1. Deploy a process definition with a non-interrupting Timer Start Event in an event subprocess and a user task in the normal flow.
      2. Start a process instance.
      3. Wait until the timer fires.
      4. Migrate the process instance.

      Observed Behavior (Required on creation):

      The timer fires again.

      Expected behavior (Required on creation):

      The time doesn't fire again.

      Root Cause (Required on prioritization):

      Since the user task is executed in the process instance scope, a target timer declaration of the timer event exists in this scope => An emerging dependent job instance is added to the migration.

      Solution Ideas (Optional):

      Check if the has already been timer triggered before adding it as an emerging dependent job instance, similar to how we do it already for non-interrupting timer boundary events [1].

      Hints (optional):

      Check if a similar problem can occur for timeout listeners.
