    Findbugs is a static analysis tool that finds NPE conditions based on the flow expressed
by the code configuration provided.  While all null dereferences it identifies are valid,
it cannot identify all potential null dereferences because the JAR may be used in another,
unevaluated context where a null reference is passed.  Therefore, static analysis is not a
substitute for defensive programming best practice, and all de-referenced parameters should
be defensively checked to be non-null.
