Compliant Solution

Program logic occasionally requires tight control over the lifetime of an object referenced from a local variable. In the unusual cases where such control is necessary, use a lexical block to limit the scope of the variable because the garbage collector can collect the object immediately when it goes out of scope [Bloch 2008].

...

It is unnecessary to set local reference variables to null when they are no longer needed in a mistaken attempt to help the garbage collector recover their spacereclaim the associated memory.
