Isso é pegadinha - mas não deve cair nada tão cabeludo. Se você vir o JavaDoc, vai ver que existem 2 métodos - “interrupted” e “isInterrupted”.

JavaDoc:

interrupted

public static boolean interrupted()

Tests whether the current thread has been interrupted. The interrupted status of the thread is cleared by this method. In other words, if this method were to be called twice in succession, the second call would return false (unless the current thread were interrupted again, after the first call had cleared its interrupted status and before the second call had examined it).

Returns:
    true if the current thread has been interrupted; false otherwise.
See Also:
    isInterrupted()

isInterrupted

public boolean isInterrupted()

Tests whether this thread has been interrupted. The interrupted status of the thread is unaffected by this method.

Returns:
    true if this thread has been interrupted; false otherwise.
See Also:
    interrupted()
