MOP: Exceptions thrown by setters of closure delegate objects are ignored; values end up in the binding

// Java delegate class
public class TheDelegate {
       public void setDelegatesPropertyThrowsException(Object value)
               throws javax.mail.internet.AddressException
       {
               throw new AddressException("Just an example.");
       }
}


// the closure call (Java)
public void methodThatTakesAClosure(Closure cl) {
       final TheDelegate delegate = new TheDelegate();

       // ...

       closure = (Closure)cl.clone();
       closure.setResolveStrategy(Closure.DELEGATE_FIRST);
       closure.setDelegate(delegate);
       closure.call(delegate); // no exception is seen here

       // ...
}

// Groovy script
thing.methodThatTakesAClosure {
       delegatesPropertyThrowsException = "tryThis"
}

assert delegatesPropertyThrowsException == "tryThis" // this was the MOP's second try
