UserTask's timeoutListenerDeclaration will be deleted from processDefinitionImpl after migrate

[FeiyuEVE]

Environment (Required on creation)

camunda 7.19.0
springboot 2.7
java 11

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

This line will remove timerDeclaration from processDefinition

camunda-bpm-platform/engine/src/main/java/org/camunda/bpm/engine/impl/migration/instance/parser/ActivityInstanceJobHandler.java

Line 130 in 47c0504

TimerDeclarationImpl declaration = activityDeclarations.remove(((TimerJobConfiguration) jobHandlerConfiguration).getTimerElementSecondaryKey());

Because shallow copy at

camunda-bpm-platform/engine/src/main/java/org/camunda/bpm/engine/impl/migration/instance/parser/ActivityInstanceJobHandler.java

Line 52 in 47c0504

Map<String, Map<String, TimerDeclarationImpl>> targetTimeoutListenerDeclarationsInEventScope = new HashMap<>(TimerDeclarationImpl.getTimeoutListenerDeclarationsForScope(activityInstance.getTargetScope()));

targetTimeoutListenerDeclarationsInEventScope's inner map —— targetTimerDeclarations points to targetTimerDeclarations which is belong to userTask of processDefinition

Steps to reproduce (Required on creation)

1. create processDefinition with multi-instance userTask (will produce 2 userTasks at least) and the userTask has a timeoutListener
2. start it
3. deploy the processDefinition again to produce a new version
4. migrate the processInstance to new version
5. the first userTaskInstance will migrate timeoutJob successfully but the rest of userTaskInstance's timeoutJob will be deleted because timerDeclaration been deleted

Not a boundary timer, but a timeout listener for user tasks

Hi @FeiyuEVE,
I keep not finding the time to try to reproduce this issue. It would be a great help if you could provide an example BPMN that reproduces the issue.

Thanks,
Gergely
