Spring State Machine Error Handling not working

[CodeYogiCo]

I am getting an exception

org.springframework.security.access.AccessDeniedException: Access is denied
	at org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:84)
	at org.springframework.statemachine.security.StateMachineSecurityInterceptor.decide(StateMachineSecurityInterceptor.java:190)

This behavior is as expected by application based on spring security. However i want to catch this exception throw it back to my api user. For the same I have written a custom listener.

public class ErrorStateMachineListener
    extends StateMachineListenerAdapter<AgreementSubStatus, AgreementEvents> {

  @Override
  public void stateMachineError(
      StateMachine<AgreementSubStatus, AgreementEvents> stateMachine, Exception exception) {
    //System.out.println("here i am -------------");
    //throw new IllegalStateTransitionException("Illegal state transition.");
  }

 @Override
  public void stateEntered(State<AgreementSubStatus, AgreementEvents> state){
   //System.out.println("here i am 2-------------"+state.getId().name());
 }
}

And registered this listener in

    builder
                .configureConfiguration()
                .withConfiguration()
                .listener(new ErrorStateMachineListener())
                .autoStartup(true)
                .and()
                .withSecurity()
                .enabled(true);

However the control never goes to this method --public void stateMachineError

Any feedback on this issue? We are having the same problem as described here. Ideally we'd like to register a global error handler that deals with exceptions rather than littering the transition configuration with , errorAction)

Hi, I saw similar question\bug report mentioned three times. Is anyone handling it?

Running into this in 2020 and it's a blocker to adoption.
