Retriy issue (Unknown method used in expression on RuntimeException)

[alef]

Hi,
consider a simple diagram with start, end and just a task service (see attachement), where the method invoked by task service only throws a RuntimeException in order to trigger a retry.
But on first retry the following exception is thrown:

ERROR 17:20:16,223 org.activiti.engine.impl.jobexecutor.ExecuteJobsRunnable - exception during job execution: Job 372503 failed

This looks like strange considering that the implementation of the method called by the task is the following:

public class MainProcess {
   private Logger logger = Logger.getLogger(this.getClass());
   
   public void doStuff() {
      logger.debug("Hello");
      throw new RuntimeException();
   }
}‍‍‍‍‍‍‍‍

Activiti configuration is attached.

Please, help me!

False alarm, sorry!!
