  36  * Exception that is thrown by the collections classes when it is detected that
  37  * a modification has been made to a data structure when this is not allowed,
  38  * such as when a collection is structurally modified while an Iterator is
  39  * operating over it. In cases where this can be detected, a
  40  * ConcurrentModificationException will be thrown. An Iterator that detects
  41  * this condition is referred to as fail-fast. Notice that this can occur
  42  * even in single-threaded designs, if you call methods out of order.
