Christian Poitras commented on STS-429:
---------------------------------------

After this discussion, I decided 3 things.
1) The serializable will be true by default. When true, I use Vadim's 
suggestion. Therefore, the result code is.
        if (object == null) {
            // If object is null, remove attribute.
            Object ret = session.getAttribute(key);
            session.removeAttribute(key);
            return ret;
        }
        else if (serializable && object instanceof Serializable) {
            Object ret = session.getAttribute(key);
            session.setAttribute(key, new MaxTimeSaver(object, maxTime));
            return ret;
        }
        else {
            Object ret = session.getAttribute(key);
            session.setAttribute(key, new NoSerializeSaver(object, maxTime));
            return ret;
        }

2) There won't be any remove attribute. It's already easy to remove fields and 
it's documented on Stripes web page. It's a simple matter of affecting null to 
field.
public Resolution cancel() {
    myField = null;
}

3) I won't add a TimeUnit attribute. John's suggestion is interesting, but Java 
5 don't support TimeUnit.MINUTES (the support is up to TimeUnit.SECONDS only).
I'll be glad to add this attribute when Stripes won't support Java 5 anymore.
