Thanks, @benhoffmann!
You were right!
In total I want to write about it for other people:
I have a case, when I have Camunda-Cockpit Spring boot app, just for monitoring the business process.
And I have Spring-boot App with Camunda engine, where I have BPMN process.
It’s a heterogeneous cluster and JobExecutor, which triggers ProcessInstance after timer tries to find in Camunda-Cockpit app and Doesn’t find it at all. For this case, I get class not found exception
Thanks for all(@aravindhrs, @Niall, @Ingo_Richtsmeier, @benhoffmann), who helped me to understand the situation!
The solution was to disable JobExecutor at all by providing property in application.properties. Camunda has property for this case.
I hope it will help other people. If someone has a question, don’t hesitate to ask me on this topic or private message.
