reported on slack: https://temporalio.slack.com/archives/CTT84KXK9/p1704733148879439

example:

public interface ParentWorkflowInterface {

    @UpdateMethod
    void foo();

}

@WorkflowInterface
public interface WorkflowInterface extends ParentWorkflowInterface {

    @WorkflowMethod
    void execute();
}

public class WorkflowImpl implements WorkflowInterface {

	@Override
	void execute() {
	
	}
	
	@Override
	void foo() {
	
	}

}

This call fails

ParentWorkflowInterface workflow = workflowClient.newWorkflowStub(ParentWorkflowInterface.class, "workflowId");
workflow.foo();
