The property will have to be documented somewhere such as the jdk.httpserver module-info. But, I'm wondering if fairly obscure properties like this might be better off "buried" in the net.properties config file. I think there's a case for putting all such "compatibility" flags somewhere out of the way like that. If we were to do that, you would need to access the property using sun.net.NetProperties.

Any other views on this?

Consider replacing this with Objects.requireNonNull

}

public void setAttribute (String name, Object value) {
if (name == null) {
throw new NullPointerException ("null name parameter");
}
if (attributes == null) {
attributes = getHttpContext().getAttributes();
