Bug migrating process instance in 6.7.2

1

Hi!
I’m using flowable 6.7.2 and looks like there’s a problem migrating process instance from one callActivity to another in this version.
Let’s say, I have a simple model like this one:

After starting the process it goes to “call activity 1”. Inside both callActivities there’s just a single user task. So the main process will stop on “call activity 1” and wait for a user task completion.
Now let’s try to migrate process instance from “call activity 1” to “call activity 2” (same model version). Suggested behavior: active token will be moved from “call activity 1” to “call activity 2”, subprocess corresponding to “call activity 1” will be deleted and a new subprocess corresponding to “call activity 2” will be started.
Real behavior: no errors, but process instance has no changes after migration.
Here’s the code I’m using for migration:

String pid = "4505147";
String definitionId = "test_migration_bug:4:4505206";

ProcessInstanceMigrationBuilder migrationBuilder = processMigrationService.createProcessInstanceMigrationBuilder();
migrationBuilder.migrateToProcessDefinition(definitionId);
ActivityMigrationMapping currentMapping = ActivityMigrationMapping.createMappingFor("Activity_1ik53m0", "Activity_0jpkzf3");
migrationBuilder.addActivityMigrationMapping(currentMapping);
migrationBuilder.migrate(pid);

Previously I used flowable 6.5 and I’m pretty sure there was no such a bug.

Here’s a process model:

I’m looking at Flowable reliability and support. I’m worried about finding bugs like this one that have no answers and is still open after a long time. Is there a rationale behind this?
