I think there is a bug in SequenceOf constructor.

    public SequenceOf(ByteQueue queue, Class<E> clazz) throws BACnetException {
        values = new ArrayList<E>();
        while (peekTagNumber(queue) != -1)
            values.add(read(queue, clazz));
    }

I used ObjectProperties to add property reference for my own bacnet object.

 		add(new ObjectType(146), new PropertyIdentifier(552), GSMPersons.class, false, false, null);

GSMPersons is a property, that contains SequenceOf<CharacterString> without any context id.

When I'm trying to read this property:

0000   00 23 54 ed 8d 5d 08 60 6e 79 44 75 08 00 45 00  .#T..].`nyDu..E.

it reads one element of sequence ("+79261314103") and then I get an exception, because ByteQueue contains only "3F", that is closing context tag of property value in read property request. And peekTagNumber(queue) is not -1.
