This class provides a MutableList wrapper around a JDK Collections ArrayList instance. All of the MutableList interface methods are supported in addition to the JDK ArrayList methods.

To create a new wrapper around an existing ArrayList instance, use the adapt(ArrayList<Object>) factory method. To create a new empty wrapper, use the newList() or newList(int) factory methods.
