The "no such value" makes me curious about the context.
The @param tag really should be saying something about the parameter.

In fact, I'm working on a method which is similar to

   /*
    * Generates some random bytes.
    *
    * @param n requested random value in bytes.
    * @param extraEntropy optional entropy caller can provide, null if none.
    */
   byte[] getRandom(int n, byte[] extraEntropy)

Most caller won't be able to provide extra entropy, but if one does have a 
dedicated device which can generate fresh entropy, it is welcome.

Alternatively, you could just add an overloaded method, and not allow a 
null value for extraEntropy:

byte[] getRandom(int n)
byte[] getRandom(int n, byte[] extraEntropy)
