In our group right now the nullability and how to indicate that and how to make it easier to read the code etc. has become the hottest topic. Wondering if there is any IG available for detecting possible NPE and warnig the developer?
Some of the suggestions have been around adding it to javadoc but that is not solid enough. Java seems to be wanting to do something in 1.5 but not sure what the current status is. Check the link below.
