Setting local reference variables to null to "help the garbage collector" is unnecessary. It adds clutter to the code and can introduce subtle bugs. Java Just-In-Time compilers (JITs) can perform an equivalent liveness analysis; in fact, most implementations do this. A related bad practice is use of a finalizer to null out references. See rule "MET18-J. Avoid using finalizers" for additional details.
