-/**
- * An implementation of {@link LazyStringList} that wraps an ArrayList. Each
- * element is either a ByteString or a String. It caches the last one requested
- * which is most likely the one needed next. This minimizes memory usage while
- * satisfying the most common use cases.
- * <p>
- * <strong>Note that this implementation is not synchronized.</strong>
- * If multiple threads access an <tt>ArrayList</tt> instance concurrently,
- * and at least one of the threads modifies the list structurally, it
- * <i>must</i> be synchronized externally. (A structural modification is
- * any operation that adds or deletes one or more elements, or explicitly
- * resizes the backing array; merely setting the value of an element is not
- * a structural modification.) This is typically accomplished by
- * synchronizing on some object that naturally encapsulates the list.
- * <p>
- * If the implementation is accessed via concurrent reads, this is thread safe.
- * Conversions are done in a thread safe manner. It's possible that the
- * conversion may happen more than once if two threads attempt to access the
- * same element and the modifications were not visible to each other, but this
- * will not result in any corruption of the list or change in behavior other
- * than performance.
