1.31 -/**
1.32 - * This exception may be thrown by methods that have detected concurrent
1.33 - * modification of an object when such modification is not permissible.
1.34 - * <p>
1.35 - * For example, it is not generally permissible for one thread to modify a Collection
1.36 - * while another thread is iterating over it. In general, the results of the
1.37 - * iteration are undefined under these circumstances. Some Iterator
1.38 - * implementations (including those of all the general purpose collection implementations
1.39 - * provided by the JRE) may choose to throw this exception if this behavior is
1.40 - * detected. Iterators that do this are known as <i>fail-fast</i> iterators,
1.41 - * as they fail quickly and cleanly, rather that risking arbitrary,
1.42 - * non-deterministic behavior at an undetermined time in the future.
1.43 - * <p>
1.44 - * Note that this exception does not always indicate that an object has
1.45 - * been concurrently modified by a <i>different</i> thread. If a single
1.46 - * thread issues a sequence of method invocations that violates the
1.47 - * contract of an object, the object may throw this exception. For
1.48 - * example, if a thread modifies a collection directly while it is
1.49 - * iterating over the collection with a fail-fast iterator, the iterator
1.50 - * will throw this exception.
1.51 - *
1.52 - * <p>Note that fail-fast behavior cannot be guaranteed as it is, generally
1.53 - * speaking, impossible to make any hard guarantees in the presence of
1.54 - * unsynchronized concurrent modification. Fail-fast operations
1.55 - * throw {@code ConcurrentModificationException} on a best-effort basis.
1.56 - * Therefore, it would be wrong to write a program that depended on this
1.57 - * exception for its correctness: <i>{@code ConcurrentModificationException}
1.58 - * should be used only to detect bugs.</i>
