/**
 * This annotation defines a Java reference to be non-null.
 * 
 * Valid references that can be marked as non-null include method return values,
 * method parameters and local variables. Such an annotation has two
 * consequences:
 * 

 * An attempt to bind a null value to the reference is a
 * compile time error.
 * Dereferencing the reference is safe, i.e., no
 * NullPointerException can occur at runtime.
