- * This exception may be thrown by methods that have detected concurrent
- * modification of a backing object when such modification is not permissible.
- * <p>
- * For example, it is not permssible for one thread to modify a Collection
- * while another thread is iterating over it. In general, the results of the
- * iteration are undefined under these circumstances. Some Iterator
- * implementations (including those of all the collection implementations
- * provided by the JDK) may choose to throw this exception if this behavior is
- * detected. Iterators that do this are known as <i>fail-fast</i> iterators,
- * as they fail quickly and cleanly, rather that risking arbitrary,
- * non-deterministic behavior at an undetermined time in the future.
