Given this code:

    /** Retrieves, but does not remove, the last element of this queue, or returns null if this queue is empty*/
    public E peekLast() {

Invoking the "Add @return tag" hint resulted in this code:

    /** Retrieves, but does not remove, the last element of this queue, or returns null if this queue is empt
	 * @return y*/
    public E peekLast() {


Note how it broke the word "empty", splitting it between the 't' and the 'y'.
In this example 'E' is a generic type parameter.
