I've almost never had a problem tracking down the cause of a null pointer. Usually just a few minutes with a debugger and getting a backtrace.
Doesn't work if the unexpected "null" sits in a graph and the source of it is hard to pinpoint or occurs "randomly". E.g. if you are using a "black box" framework or it happens spuriously on a server because it is triggered by a database timeout which never happens on the dev server.
