Camunda 8

• Camunda 8 Run works fine with Java 21, but doesn't work properly with Java 25
• Launching Camunda 8 Run along with client programs as script connector runtime on the same machine may fail due to port conflict(s). Default 8080 port is indeed often the source of failure. Port checking is then often required

Windows PowerShell

Test-NetConnection -ComputerName localhost -Port 8080
# Alternative:
netstat -ano | Select-String ":8080"

• Migration from Camunda 7 to Camunda 8 ☛
• Camunda 8 does not support the totality of BPMN ☛. As an illustration, BPMN conditional event ☛ is supported by Camunda 7 and (graphically) within the Camunda Modeler while it is not supported at run-time by Camunda 8

Camunda 8 Run ☛ and ☛ is a lightweight container for BPMN execution. Spring Boot (Java) or Node.js (JavaScript/TypeScript) are support platforms for writing client code that interacts with Camunda 8 Run ☛

Operate console ☛ with demo demo as credentials (./configuration/application.yaml) allows the access to the runtime status of deployed and instantiated BPMN processes. Other accesses are described in the ./endpoints.txt file
