/**
 * Parse the next value as an object. If the next value is {@link JsonToken#NULL}, returns
 * null./*  w w w .  ja  v  a2s .c  om*/
 * <p/>
 * This method will use the provide parser, or if none is provided, will attempt find an
 * appropriate parser based on the discrimination value found in the next object. If none is
 * found, then this method returns a {@link JSONObject}.
 *
 * @param reader The JsonReader to use. Calls to {@link JsonReader#beginObject()} and {@link
 * JsonReader#endObject()} will be taken care of by this method.
 * @param parser The parser to use, or null if this method should find an appropriate one on its
 * own.
 * @param key The key corresponding to the current value. This is used to make more useful error
 * messages.
 * @param expectedType The expected class of the resulting object. If the result is not an
 * instance of this class, an exception is thrown.
 *
 * @throws IllegalStateException if the resulting object is not an instance of {@code
 * expectedType}.
