How to make custom Alfresco AMP action fail?

Question

I have developed a custom AMP action for Alfresco repo. I want Alfresco to understand that the action is failed if some condition is not satisfied and as a result show the failure message in pop-up.

I have written the followings in executeImpl method but the action does not fail if condition is not satisfied.

@Override
protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {
    if (condition) {
    // Do something
    } else {
           ((ActionImpl) action).setExecutionEndDate(new Date());
           ((ActionImpl) action).setExecutionStatus(ActionStatus.Failed);
           ((ActionImpl) action).setExecutionFailureMessage("Action is failed");
           throw new RuntimeException("Action is failed");                        
           }
    }

Alfresco considers that the action is executed successfully. Yes, I have defined failure and success messages in share-config-custom.xml. Is there any way to manage the action in this context?

I have tried throwing RuntimeException, ActionServiceException but I don't know why throwing a WebScriptException works. Leaving the answer here if someone is looking for it:

@Override
protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {
    if (condition) {
    // Do something
    } else {
           throw new WebScriptException("Action is failed");                        
           }
    }
